I think there are two issues:

1. It sure would be nice if there were some "choose my experience" features at a broader scale than individually taking responsibility for blocking all the noisy instances and noisy people, for whatever your personal definition of noise is. A checkbox like "hide political content" or "downplay political content", and then similar checkboxes for meme content, content for a particular geographical region, popular media and entertainment, and so on, would be an absolutely wonderful thing. I think PieFed has something somewhat similar to this but it's at about 10% of where it could be. I think Lemmy inherited Reddit's "you can either have the default or else invest a huge amount of time into customizing" model, but it doesn't need to. We should have a lot more rich ways of deciding what the algorithm and experience is going to be than just a massive array of individual "yes" or "no" buttons.
2. Some of why your suggestion would be nice is cultural, not technical. People seem like they like to have their "home" instance where they can kind of make friends and read content from like-minded people, irrespective of how whatever algorithm is tuned. Personally I love political content and news, but I could see an instance that just turns it all off for people who aren't into it being a rare island of wholesome interactions on Lemmy, simply because of the types of people who would choose to go there. We can go back to watching the world falling down around us some other time.

I would argue something like starter packs would be a better fit for this particular feature.

I would counter and suggest that Lemmy implements a "default block" system that admins can set on their instance, i.e. the 3 you've mentioned, plus any others they want. When the account is created, the default blocks are applied (either instance or communities or ideally flexibility to add both).

Users can then choose to unblock these if they want to engage with that content without moving instance.

While portability is kind of a feature of the lemmyverse, your posts don't come with you so likely people wouldn't want to move off the "default" instance, which would create another problem with centralized instances.

I think themed social sites are the way to go for the fediverse, almost to the point where the theme doesn't matter. Any theme. Any raison d'etre beyond "to be a general interest clone of what already exists". So yeah, I think this is a good idea.

I think the suggestion also highlights some moderation/administration features that were missing when I first tinkered with self-hosting Lemmy a year ago. Are there tools to allow users to access these types of communities while keeping them hidden from the 'All' feed? There wasn't last year. It would be ideal to designate sites and communities that are A) totally blocked/banned, B) accessible/subscribable but only via direct url search, C) searchable, but not available in All (or even local, for hidden local communities), D) accessible via All. Or even having different discovery vectors selectable via binary selection. The fine grained filtering to do such a thing would be a real boon in general, especially for sites that want to remain thematically focused, while not handcuffing users who want to be able to view stuff that's off-topic.

Would you guys quit shittin all over blaze? Not everything is politcal. The issue is people making everything political. How the fuck are cat memes and let's say makeup, political? They're not.

Some ppl just won't shut the fuck up about politics and it's super annoying. I think it's a great idea blaze has.

Me liking printed books more than ebooks is already a political matter, so... that would be difficult to offer political-free content.

I think I already mentioned it, but my idea would be to have nothing for newcomers (so they don't get to see even a single political, or low effort post) beside a few tags/keywords/categories they could click in order to start having content displayed in their feed that they actually want to see, no matter how good or how bad it would be ;)

edit: typos

If you removed political content from Lemmy there would be nothing left. All the other communities are dead.
