I can't speak for all Chelsea fans but I know a lot of fans that are like me, that is to say, quite reserved talking to other fans, not wanting to announce our loyalties and hear all of the **** we ALWAYS hear the second someone knows you are a Chelsea fan, don't go around wearing Chelsea shirts...
Honestly, if you announce yourself as a Chelsea fan most of the time you can't even argue a point because all you hear back is Chelsea Headhunters, Roman Abramovich, no history, yadda yadda yadda. **** off
