So if these are people wiring their Christmas lights wrong, assuming these are led lights, doesn't this "solution" not work bc of the polarity anyway? Or is that only a DC thing with diodes? I only did okay in my physics electricity stuff lol

For simple stuff such as those lights, polarity is usually not a problem when using AC.
In case of AC (Alternating Current), instead of having a + and - pole, you have a Line and a Neutral terminal.
The Line terminal goes + ... - ... + ... - ... + ... - with time and the Neutral stays at 0.
When connecting to LEDs and such, you have an AC to DC converter, which tends to be fine no matter which pin you put in which hole.
Edit for clarity: I am talking only about the specific appliance in this case, having a 2 pin plug. When doing home wiring, polarity matters a lot.

No, alternating current doesn’t have a polarity like DC does.

I made one of those once by accident. I was talking a long extension cord that had been cut in two and converting it into two smaller cords. I messed up and attached the male to the wrong cable.

Also known as a "nope rope"
I thought that was a snake....
Those are danger noodles
What what's a safe danger noodle then? I thought those were nope ropes.

I wouldn't plug both ends of a snake into the mains either.

They very much do exist, though. Often used sketchily with generators.
How do you non-sketchily feed a generator's power into your home?
Lol this dude never turned hydro into diesel! Look at this guy!
Technical details and the social contract mandate that your generator is never connected to the main power grid. The generator should be wired to an enclosed AC transfer switch. This switch will connect either the generator or the main grid to your home, but never both.
Some detail: If the generator is wired to the main grid it can prevent restoration of main grid power. While an AC transfer switch will perform the task, many jurisdictions mandate additional safety precautions (which can be quite expensive).
It can also kill a lineman working on the power lines outside your house, thinking they’re not energized.
It could. But, there's more layers to this swiss cheese model of safety. For example, the lineman's procedure is to ground out, then isolate, then test. They'd need to skip both ground out and test to be electrocuted by an asshole with a generator.

The real way is a generator inlet, which is a male plug that's interlocked with the main. So the cord ends up being a normal male/female cord
There are electrical panel accessories that automatically isolate the house
You get a qualified tradesperson to wire it properly into your electrical distribution.

Modern inverters do this somewhat safely by sensing the phase before outputting power.
Of course, you can’t tell just by looking, so I still would steer clear of the whole thing on principle.
I thought this was an anti homosexuality meme until I read the top comment.
I've got to stop using Lemmy. It is changing me...
I too have developed into a very politically correct person with lemmy, I kinda miss being able to make gay jokes
Gay jokes as in just jokes making fun of gay people? Why do you miss making that? I can just tell you that especially when I was a gay kid, I would have wished no-one would make such.

I guess you're too straight edge for that.
God, straight edge is so old I literally had to get a consultation to understand the insult

It's also good to backfeed a generator into an outlet
