A heretic is usually someone who violates TOS with some expectations. We here at the Crusader stream don't hate furries in fact a large number of us are furries (with the expectation of Mine_Turtle whose a refugee of the AAA and the anti furries who were both recently dissolved) most anti furry memes are just jokes. Furries themselves are not heretics.
Furries i think aren't exactly heresy, but they are suspicious. most furry activities from an outside view are... questionable. Though don't quote me, i'm new here
