There's a difference between jocks and athletes. Athletes are sympathetic. They're not bositerous, they play because they love the sport. Many Olympians are athletes, and I love watchng them. Also, many people that play soccer (not just the pros) are athletes. They're nice to people. Many also have a normal figure.
However, jocks play sports because their couch-dad made them. They play it for scholarships since they're too stupid to make it into University otherwise. They play to get girls, and to get away with doing stupid things, such as drinking in excess. Jocks are a subgroup of Bros, which are basically the same thing but don't necessarily have to be athletic. They are usually monstrous and try to use their size to intimdate. Many play American Football.
I wasn't bullied that much, but when I was, it was the dumbass jocks in physical education class. I hated phys. ed. for this very reason. I suck at sports. I'm not that "manly". Jocks look for weakness in other guys so they can exploit it in order to assert dominance. They like to think of themselves as alpha males. I like to think of them as idiots. All of the asshats that called me "fag" and pushed me around are now doing shit-all with their lives.
Not to mention the jock girls. They're the bitchiest girls I have ever had the misfortune of talking to.
So yes, I do carry a grudge against jocks. Not fit people. But jocks.
