I hear what you are saying. But I would say even if we don't mute what we disagree with, it doesn't necessarily mean we won't be open to growth. I think the willingness to learn and grow is almost a conscious decision, and part of that is creating the environment we want to be exposed to. My personal thoughts on your post.

I’m happy for people to raise alternative points of view in a civil discussion, but have no qualms about blocking trolls or ad hominums

Most social media is like that anyway to an extent

I block people who espouse any form of USAsian political garbage. Also anyone who starts in with personal attacks instead of rational discussion
