Hating The Beatles nowadays is not the social crux people make it out to be. I mean, really. I know people who personally loathe them (none of them play an instrument, what a coincidence) and nobody ever calls them for it. They're such a popular band that they're bound to have as many if not more detractors. For every Christian, there is an atheist.
But the funny thing is, asking someone why they dislike them is what agitates them the most. "WHAT??? DUDE, CALM THE FUCK DOWN. IT'S OKAY IF I DON'T LIKE THEM!!!!" is the typical response. It's like they think you're about to turn into a werewolf.
