Then I have no idea what you're talking about. I've seen conservative points of view on here. Many mild enough I just disagreed and moved on. Some I didn't even see a need to respond to.
I still think you're conflating "supporting nazis" with conservatism. One thing you may want to consider here is that many who chose Mastodon over the corporate platforms are within those groups that the far right wants to enslave or kill. Thus you will see a higher tendency to block, yes.
