The fact that you are un-offended by insults does not give you the right to be insulting to others.
I come to play games, and check out things on the forums.
I don't like getting called 'faggot' and i don't call other people by those terms.
Ditto 'nigger' 'slut' 'whore' and a whole other slew of nasty words, some of which i have had levelled at me.
Racial, sexual, and gender slurs are not appropriate in civilized society.
And while some parts of the internet are wild and unregulated, this is not one of those places.
I notice that you have yet to apologise, nor have you uttered a single word that lets anyone know that you recognize your error.
In truth, you've laughed it off, and effectively told everyone that they are over-reacting.
Actions have consequences. This is one of them.
