I can see why people get frustrated with humans, we're a species that can't handle the fact that individuals have different skin colours or different sexual orientation or general opinions, we rarely are nice and kind to one another and we're basically destroying our own habitat. But spending every living waking moment hating people wastes too much precious time and energy. There are good things on this planet and every human has their good and bad points.
It's actually quite possible to get along with people who you have nothing in common with. I know many who are interested in stuff like TOWIE and it's still quite possible to find positive points about them. One of the most funniest girls I ever known in school would have been referred to by others as a 'chav' and 'not clever', but I genuinely got along with her, despite having very little in common.
Also, being an introvert is no way linked to being a misanthrope. You main gain energy by being on your own, but it doesn't automatically mean you're a misanthrope.
