Funny enough, I made a post in another community specifically about blocking. On the one hand I agree with you as for the curated experience, on the other hand echo chambers are unhealthy.
Its a very difficult balance to strike. Thus far I have only blocked communities which have zero bearing in my life - languages I don't speak, kinks I simply don't share, etc. However, blocking individuals is something I frankly hesitate to do because even the literal worst POV out there is useful; its good to know where the extremes lie and to be prepared for that level of madness.
At least, that's my opinion. And thankfully I find so far that even the most absurd hot take that I disagree with wildly on this site is still more palatable to me than half the crap that was out there on reddit before I left. And even those with snark are often kinder about it than reddit, I find.
In fact, I seem to be the barely-palatable-hot-take here as often as not, but given upvotes are entirely meaningless in all ways and especially to my actual daily life I generally am not bothered by it.
