I'm personally fine with it, as long as you don't jump into an unrelated conversation and say "I'm a furry."
I don't feel like finding my quote, but it went deeper into this point.
Edit:
Oh, and people will hate you if you like something they don't, such as Halo, Runescape, and furry research. I don't hate these people, as said above, I only hate the people who try to get attention by saying "I'm a ____!" when the conversation had nothing to do with whatever the forget they said.
Example:
Chrono: So how are you today?
Person A: Great. So how is that build comming along?
Person B has connected to the server.
Person B: I'M GAY!!!!!!!
Chrono has permenently banned Person B (ID: ####). Reason: Attention whore.
