I have never at any point encountered "super right wing" people on any main Matrix server. I've seen a lot of the opposite, to the point where it seemed administration was unfairly strict on people they considered part of them, while letting the other side run rampant. I somehow doubt this.

The only time I've encountered anything of this description is when I was looking into why a server had been defederated, and then found out it was mostly neo nazis and weirdos obsessed with anime children. I had to actively seek them out to discover this.
