It’s a combination of Hexbear having a higher population of well-read communists and anarchists than most instances, and your guess that there are so many bad-faith responses that they are quickly shut down. Hexbear also doesn’t have downvotes, so people are forced to actually reply if they want to express why they disagree.

As I said in the other comment, once you stepped back and clarified your position more, you were treated better.
