I don't understand what about it offends you.
I made a pretty long-winded rant about how furries should stay locked up in their fursuit closet. It was knowledge from direct experience on top of that since the forum I'm from had a huge deal with furries and ended up perma-banning every single furry there because everyone was just fed up with them being tremendous friends.
Here's how it goes. Generally furries want to be universally accepted on the internet, so they post their furry things and you know, generally come out of the closet. They like to flaunt their furry stuff in order to try to convert people for some reason (see Tails' avatar as an example, Packer's last avatar which was removed). Now the thing is people make fun of them, which is pretty much normal on the internet where people will make fun of everything and everyone. But, instead of just taking the joke, furries will get upset and retaliate as much as they can. Ok fine, so what's the big deal here? They take it way too loving far.
Where I came from it got so bad that the furries were referring to themselves as a race (of animal/human hybrids), and calling everyone national socialists trying to kill them, claiming they were receiving death threats, etc. They were mass banned ultimately for disobeying rules as a group (no research, no mind loving images, no stupid stuff). But still up to that point I learned pretty much everything there is to know about furries, and that's why I hate them.
The only good kind of furry is the one that doesn't loving spurt out that he's a furry, to everyone's knowledge such a being does not exist.
