Jeez I'd have HATED to be the one teaching you to drive or even ride a bike. Its the same reason most console gamers can't use a keyboard and mouse; you aren't used to it. Just like getting good at PC games it takes practice (ever watch Seananners or Grizz play COD?). I play some FPSes on my 360, like Black Ops and MW2 (OMMGGEERRRZZ GET OUTT!!11!!!1one!111!) but I'm also an avid RO/ARMA/etc player and a developer for RnL. I can do fairly well on 360 but I'm better on PC because I have been playing online shooters since Delta Force.
Elitism is hilarious.
To be perfectly honest, I have some experience with consoles and their horrid controllers. You can probably play MW2 as well as any PC user out there I'll give you that. But unfortunately that game is very very bland when it comes to aiming, controller or mouse, the input method doesn't really matter because it isn't used at the level where a controller would face difficulties.
Take a game like Quake on the other hand which makes it absolutely impossible to strafejump, perform flickshots and switch to different weapons on the go, and no I'm not talking about "press a button to switch to next weapon" I'm talking about pressing the exact button needed for that particular weapon. There's a good reason why they don't use controllers at world championships.
You say you've played ARMA, let me ask you this: How would you feel if ARMA3 was a console port and many features had to be taken out because a controller does not have nearly enough input possibilities?
How would you respond when every sequal to the game you love gets dumbed down to fit the casualness of the console users, even IF you're on the minority who actually does not play the console casually.
How do you accept the fact that due to the non/slow-changing hardware configurations of console hardware, development of games lack innovation on certain aspects because developers are stuck with the same hardware for atleast 5 years.
This is all "Elitism" you say? Perhaps you're right, but atleast PC gamers want to see improvement where as the average(note: not everyone) console gamer only looks to play with their friends on the couch, and will happily pay for and play crappy games. The worst thing is, publishers like Activision are fully aware of this, which is absolutely the reason why CoD has 10x the players on the console.
Not everyone here has good reasons to dislike consoles and their controllers. I even liked consoles much better in the days of Atari. But those days are over.
