Inverted.
First games I played using a joystick were flight sims and the like. I hold controllers more or less horizontal, and back then they were fixed to be horizontal, so in my mind forward and back are 'pitch forward' and 'pitch back.' It stuck, and now, regardless of game or game type, it's become counter-intuitive to use the normal setting.
I agree with the first poster in that I don't see what the big deal is. It takes about 8 seconds to set up a controller and then everyone can play the game their way. There doesn't need to be a discussion about it past simple curiosity. And really, with all the other ways to prove superiority in games that someone resorting to mocking a personal choice in controller setup rather reeks of a sore loser, or a sore winner.
Myself, I appreciate when a game has complete controller customisation. Set it up however you want and the game's like slipping on a comfortable, old shoe.
