Okay, I'm going to break this down for you. You were a cunt in this situation. Here on FPH, we can act like as much of a dickhead as we want and face very few -- if any -- real-world consequences. For all intents and purposes, FPH is, essentially, a safe-space for those of us who disagree with the common-held belief that obesity is anything but your own fault.  On Facebook, however, you need to act like a human. You are broadcasting your opinions to people that you interact with on a daily basis. You just can't go around telling people that, something as arbitrary as their personal taste, is shit. That's how you find yourself alone, on New Years, with no friends, playing Overwatch. Arguing about whether a musical genre that you dislike has any legitimate artistic merit to it is such a futile, worthless argument. Even if you did win the argument, where would you stand socially with those people? Would the people that you flipped to your side like you more as a person? Or would they resent you for making them think something they invested their time in was not worth their investment? On top of insulting their personal taste, you then went on to call a teen-aged girl fat. This is easily one of the most hurtful things you can tell any budding woman who cares about her looks. As mentioned previously, the hard held thought today, is that obesity relies on many other factors other than what you cram into your maw. So, with that in mind, you essentially told this girl "You think you're black. Your musical taste is shit. And that auto-immune disorder you have makes you ugly."  You are the biggest asshole to these group of women right now, man. If they have any social pull at all, and you're in high school -- which I assume you are -- you can kiss your chances of getting laid good-fucking-bye. Not even laid by these girls, but just in general. Women talk among each other a lot. It's not unlikely that one of these girls is friend's with a pretty girl, or a popular girl. If you think that they won't mention how you called them fat, you're not being realistic. As for your assessment of K-Pop not being "original", what constitutes originality? Is originality authenticity? How do you achievement authenticity? Is it rapping about how you grew up poverty-stricken? Is it picking up a guitar and signing about how you want to erect a wall between you and your fans? Is it pork-pie hats and banjos? Authenticity, again, is arbitrary. Music is subjective. You were being rude.
