No Stupid Questions

Because conservatism is no longer a set of political beliefs. In the modern conservative movement (basically starting in the 80s, liberals and conservatives were much different before that) conservatives had social beliefs, like preserving cultural norms, promoting religion, and maintaining the nuclear family, as well as fiscal beliefs, like limited government, individual liberty, fiscal responsibility, free markets, and a whole lot of other bullshit that basically boiled down to, "we don't want to pay taxes."

Now, conservatism is really only about establishing an in-group and othering their opponents. Oppositions to trans rights may seem like an attempt to preserve cultural norms, but it's real goal is to create outrage and panic over trans, "groomers." Objections go CRT and DEI serve a similar role in othering people of color. "Wokeness," is just a meaningless catch-all for, "enemies." Similarly, fiscal policy is meaningless, and can be picked up and discarded whenever convenient; corporations can be deregulated and given tax breaks in service of the free market, but subsidized or bailed out whenever needed.

This is because modern conservatism isn't a political ideology, it's a fascist movement. I mean that literally, and while the meaning fascism is notoriously hard to pin down, I use Umberto Eco's 14 properties of fascism. And, to bring this back around to your original question, fascists hate liberals because hating a group is very important to a fascist movement. The modern conservative hate for liberals is especially clear in Eco's 4th, 5th, and 7th properties of fascism (disagreement as treason, fear of differences, and obsession with plots, respectively).

So, tl;dr: the one-sided hate that conservatives have for liberals is because conservatism is no longer a coherent political ideology, it's a fascist movement.

I'm going to make a second comment, from the point of observation bias:

OP obviously knows people who have been attacked by vicious, hateful people on the right. But OP is probably hanging around neither the people on the right being attacked by vicious, hateful people on the left, nor around the vicious, hateful minority of the left who are attacking people on the right.

So she hasn't seen it. But I have. I've been attacked from the right for my progressive views and from the left for my conservative views, and from both by people who assume that if I think A I must also think B and C, no matter how benign A is and horrific C is.

Thats a loaded question if I've ever seen one.

I live in a heavily liberal city but have unhinged rightie friends in other states, including Texas amd Florida. The most unhinged ultra maga shit I see on their feed goes blow for blow with the brainless, bitter, amd sometimes hateful nonsense I see coming from my lefty friends feeds.

If one is a hateful loser of a certain ideology, they naturally blame the other side. It's human nature.

Saw a cartoon years ago. Panel 1 = "How Democrats See The World." It's a globe with the USA divided into Red States and Blue States. The rest of the countries are pink/green/orange except for a few black spots with a skull and crossbones marked 'Terrorists.'

Panel 2 = "How the GOP Sees the World.." Same globe, except there are only two colors; the Red States and everything else is "Terrorists."

I’d have to spend time looking through conservative nonsense to make memes about it. I don’t care to appeal to the lowest common denominator.

Fetishization of the concept of civility. Liberals have always preferred a negative peace to even incredibly mild disruption, and that'd include hating people who want nothing more than to see the world worse for everyone. Hang out with leftists instead if you want to see people rightfully angry.

Assuming that you used "liberals" to refer colloquially to the American left wing and "conservatives" to mean the right...

You do see the inverse. You see it in this thread: Calling conservatives rats, saying they don't have morals. I just read all the current answers, and less than a third of them made any attempts to understand those on the right instead of othering them.

Can't speak for anyone but me on this one. It's the same reason I don't hate anyone, really. We're all unique with completely different perspectives on the world, perspectives that naturally lead us to different conclusions. Me hating someone will only push them into their own world. I'd rather share my perspective, and hope it moves theirs a bit, so that we might reach a better common ground.

Because liberals see "the world vs the ideal world" we see problems and we try to correct them.

Conservatives see "us vs them" and burning the world to the ground is fine as long as "The others" burn with it.

USA here. They'd likely consider this to be extremely patronizing, but I consider most conservative voters to be unaware of what it is they are actually preaching. It's crazy but the more extreme their views get, the more I'm convinced they're misinformed and misled. Some folks at the top of their pyramid I legitimately hate - I have no doubt they know exactly what they are doing.

So many of conservative beliefs just fly in the face of reality. I hate that they're perpetuating the harm that the beliefs and resulting policies cause, but seeing as how they are mostly based on clear and obvious lies, I have to assume that most of the supporters just don't realize they are being lied to and have invested emotionally in an identity that actively harms their own interests.

Many many liberals were raised by conservatives.

Many many conservatives raised eventual liberals and are aghast.

I don't need to camp out and bully conservatives. I spent enough of my childhood immersed in their insanity. I'm just done.

Conservatives are afraid. They (at least the professionals and the GOP as an organisation) are well aware that they are on course to get irrelevent in the future. Not only are their politicians getting older, their voter base is getting older and shrinking. So the try everything in the book to stay relevant: Gerrymandering, reducing access to the voting process fro people who are unlikely to vote for them, etc. And as we all know, fear, or worse, existencial dread, leads to hate for the other side, the group of people seen as their very threat to their existence.

They are basically cornered rats, clawing and biting the pest control man.

Joke: Why hate the disabled?

You go high, we go low

People on the left don't tend to act like people on the right and people on the right know that and exploit it.

What now? Why do you think the premise is true?
