I just remembered one. People who pirate things, get busted by anti-piracy measures and then bitch and moan about being discriminated against. WTF? Yeah, I haven't bought everything that I have on my harddrive, but I'm not going to cry foul if something doesn't work because I was too cheap to buy it. Bawwww, you can't play a game online because you're being discriminated against for stealing the game, your logic is flawless.
My personal favorite is that I've never pirated anything that didn't work (with the exception of online play) after being appropriately cracked - but I have PURCHASED things with anti-piracy measures that prevented them from working on my system.
And only twats play games online anyway. Singleplayer > *.
