I never really got what makes one an Anti-Fur or TERF.
Lack of confidence?
Boredom?
Fear that marginalized people get rights?
Fear that things that are normal since millennia get normalized?
Attention?
I can't really put myself in the mindset of waking up and going "Oh wow I am logging into [thing] fansite and hate on [thing]".
e. g. I never watched a justin bieber music video just to dislike it and annoy the fans even though the hate was mainstream back then
