Using a controller for shooting games is like being gay. Some people just have different preferences. But the 'normal' keyboard and mouse users look down on us controller users, belittling us with petty insults and hate speech, calling us gay, and consolefags. Slowly controller usage is becoming a more and more acceptable thing, but there will always be those extremists who will continue to protest the 'abomination' no matter how socially acceptable it becomes. At heart these people are jsut afraid if they tried a controller they might like it.
