Furry is about the anthropomorphic and animals. Meaning animals become more human. Sex, however is part of humanity and culture. Thus of course there's going to be that kind of anthropomorphic as well.
Humanity, with all it's flaws and nuances is anthropomorphism in the fandom. There is never any absolutes in this world, and those that can't understand culture and humanity and that pointing to an example to enshroud an entire group should never hold any power other then feeding and clothing themselves.
No, furry itself is not about sex.
