I’m with you in spirit if not numbers. My experience with hexbear users led me to blocking the whole instance, and I regularly block people I don’t even converse with based on how they treat other users or other topics. If someone has such a bad take on topic A, I don’t care about their possible opinions on topic B and C in the future.

I get the argument of echo chamber isolation, but most of the things I’m willing to block people over are also things that I won’t be changing my mind about because of a forum post.
