The Bio in your profile is just an opportunity to let folks know a little about your background. What you do/did for a living, hobbies, etc. If there's something in there that you think might be offensive to someone, I'd strongly suggest leaving that part out.
If you're really not sure, then run it by a moderator or staff member through a Private Message before you fill out that part.
