Not all people are nice.
We were all born good and innocent, I agree with that. Still, some of us grow up to be complete assholes. There's no need to pretend otherwise.
So, no, I don't like everyone, simply because they exist. I respect all human beings and give everyone a chance, or at least I try really hard to. But when I see a traitor, a pathological liar or a hypocrite, I don't pretend to look at Gandhi.
I like very few people. Those who consistently demonstrate that they live by the values I observe as well.
Being excluded by some groups comes as a compliment. They confirm I have not forgotten what is important in life.
