This person is most likely a custodian of some kind, perhaps a plumber's assistant.
He is one of those aggressive cretins that provides entertainment by the absence of self-awareness; i.e. doesn't know that he is an imbecile.

oh the shock, the horror, how dare he say the things I want to but allow fear to hold me back.
In all seriousness, [MENTION=3627]Silverback[/MENTION]; surely you're old enough to say and do what you want without giving a fuck about other peoples perceived self awareness, no ones gonna give a fuck when we're dead man. It's not like history will remember guys like us, arseholes or socially constrained nice guys don't matter, we'll be lucky if half a generation give a fuck once we're rotting in the ground.
social constraint is the shackle that keeps morons from been told their morons, so you hurt a few feelings along the way, swinging your dick through life, really who cares it's not like it's going to reverse the earth on its axis, your just gonna upset some people who's displeasure is totally inconsequential anyway.
Maybe you'll do them a favour and offend them into some action, snap them out of their apathy?
