I honestly can't help but hate being around my younger brother. I am thinking part of it might be me being sensitive/insecure, but he has this habit of being so opinionated about everything in a way which I find to be offensive. And it's not about things that matter, like where there is actually a right and wrong, it's usually about things like shows, movies and video games. Normally when people express an opinion contrary to my own about these things, I am perfectly fine with it. But when he does it, he is basically implying that his opinion is fact, like it is not just his opinion, but that the show/movie/game he doesn't like is objectively bad. He sits there and explains in detail why it is as he says it is, and his explanations usually have negative connotations for the people who have the opposite opinion. For example, he bashes network television, claiming that the shows are not as good because the shows are made for a mainstream audience, and therefore aren't as "smart". Lately he has become obsessed with "feminist" issues, and his latest thing is that he will get hung up on sexist aspects of a show/movie/game and keep pointing these things out to argue that the show/movie/game is bad and, implicitly, that those who like it are wrong and should change their opinion.

Does anybody else find people like this intolerable? Or am I being overly sensitive?
