Hi. My response to that would be (and is) rather political. It may not be viewed as appropriate to mention that here and I'll let you decide whatever it's something you want to have here or not (just as I let you decide whom to have on your friends-list and whom to play games with or not.. I can't really understand how that's a hard concept to grasp =P, guess I could even have answered just that: You deserve the right to pick whom to befriend and play games with and that's simply how things are.)
Anyway, the long response I put on http://pastebin.com/aVpDU2yd. If you wanted it here I could repost it, but I don't see how you'd care, if you don't want it at all and don't think it's approprate just tell me to delete it and I'll delete it and replace it with the message about how people on Steam of course should be free to pick their own friends and play or not play with whomever they want :).
More "inappropriate": http://pastebin.com/XfnbtNmW (Not in my mind but I sorta have to accept the system.)
