Intelligence? All games require a level of intelligence to play well that's a given. There's no right or wrong way to play a game, but its naive to think controller has equal opportunity.
You can disagree all you want, that doesn't make it any more right nor does you linking to something that shows keyboarders beat controller users. There are many things to factor in beyond the controller whether you want to accept that or not. I can speak from first hand knowledge in how much or little "better" a keyboard/mouse player can be over a controller player. A keyboard / mouse is 100% restricted to the exact same game mechanics as a controller and you saying otherwise without first hand experience is shear stupidity.
You are naive for thinking that gaming smarts is not much more important than outright shooting and that has been proven as well. What do you think actually separates professional gamers who's aim and reflexes are almost identical? It is their smarts of the game.
Me being a well above average mouse player can tell you that according to you and your link there shouldn't be a single controller person out there that can beat me. Well I can certainly tell you that you are wrong and that again is from first hand knowledge and not just me spouting off hearsay as you are.
So until you actually have the first hand knowledge to speak on the subject, keep your foot out of your mouth and remain silent.
