We all need a vent from time to time, and Johan has decided that this is where he gets to have his venting needs met.
Let the man vent, he isn't actually hurting anybody. Considering the rife preponderance of thinly veiled racism so frequently found in the comments on political stories  here, like a silent breaking of wind in an elevator you can't quite point a finger at the guilty but we all suffer for having to experience them... compared to all that, Johan's little vents are just the whiffs that float under the stall doors, bothersome but accepted as an unavoidable consequence of a need we all share.
