You lost me at 'Weird, prentious Art-House mods for Half-Life 2'.
But seriously, Counter-Strike is the Halo of the PC. I'm suprised you didn't get a face full of terrorist crotch and a carefully worded (yet appalingly spelled) essay on why you're gay, who you're gay with, and the precise details of your sordid affair.
As for that postman, well, you're always going to get nutjobs. I personally know quite a number of people (not all old men, mind you), who think Women's rights are a joke, get back in the kitchen etc.
In fact, I get the feeling that as a gamer, you're more likely to be accepted as Gay: the majority of 'hardcore' gamers are in the 18-24/30 bracket, and as such are all memebers of Gen X/Y; the most accomodating and accepting western generation to date.
The point is, you're just as likely to get called a 'retard' as you are a 'fag'. I should find this offensive (I have Asperger's syndrome, quite acute-bird............................), but it's just part of the background noise when you're playing online. Usually nothing is meant by it, and (unless you're playing on that hive of idiocy, Xbox Live) if you explain that you take offence, most people will try to avoid using certain words and phrases.
A problem I have is that often, in game, a gay/lesbian/furry/woman/scatologist/all-of-the-above etc. will muscle their way in, and demand that we walk around of eggshells in the off-chance that we say something even slightly offensive. Not to mention they usually get huffy when we don't treat them with the utmost respect because "I'm gay, damnit, look at how brave I am to come out to people on the internet". But, I suppose the G.I.F.T. works on everybody, regardless of sexual preference.
... Bloody hell this is turning into an article all of itself, so I think I'll stop no, the hole is plenty deep already.
