It's not that PC gamers have a "hatred" of console gaming, it's, that console gaming is inherently a casual gamer thing. That doesn't make it "bad". But, when launched, consoles are usually based on tech that is already about a year old by PC measures (since they need to develop on that architecture, while it hits PCs immediately), and they don't improve, unlike PCs. The input scheme is designed around a specific controller, rather than keyboard/mouse and all the macro key variation you can get. Plus, for things like FPS shooters, a mouse provides significantly more detailed and accurate aiming than a controller is capable of.
That's not to say you can't be pro on a console. But it's by console terms. It's like topping DPS in LFR. The tech isn't cutting edge, and the input schemes aren't flexible and accurate enough.
Which is fine, I want to emphasize. I've got a Wii myself. But every time I see a PS3/Xbox 360 gamer diss on the Wii for hardware limitations, my response is always "your consoles were that much if not further behind PCs the day they launched, and have only gotten further behind since". If you want cutting-edge graphics and performance, you game on PC. Consoles will always be the cheaper mass-market version.
