Sometimes I pity those that just assume we are all sick. What's even worse are those that want us to die. Die for what? What have we done that's sooooo bad that we deserve to die? What bothers me the most is that there are communities out there bent on "fursecution" and other ridiculous stuff. For example, Flash Flash Revolution is supposed to be a Stepmania site, but they loath furries there. Infact, I even heard someone say this.
God created all equal. No one deserves hate. ...Except furries. They're [Insert Insult] and can [Insert Cliched Furry Insult]
Normal trolls I'm fine with and can laugh at, it's the ones that think we deserve death just for being furries that bother me.
Edit: But while I do get annoyed by stuff like that, I usually just try to make a point without raging. I tell them calmly why they are in the wrong, and they keep blabbing on about how sick we are, repeating their words over and over, and I keep telling them my points. It hardly ever gets through to them, though, but at least I tried. But normally, the persistent ones are the failtrolls, the ones that make me laugh. Normal trolls usually get the hint that I'm not going to blow up at them, some even congratulate me for handling a situation well.
