I agree with the post in regards to racism, but that's about it. It's much better to loathe people as individuals than widespread groups. Except for hippies. And emo kids. Fuck them.
AFAIC, everyone has an opinion on everyone, including myself. Do the people in which you feel negatively opinionated towards deserve to have you openly critisize them in situations where they've done nothing to wrong you, haven't directly created any problems for your well being? I'd answer no.
It feels like anyone who wishes to share their hate of certain social groups or ethnicities all the time make any excuse, argue any way they can to hide the fact they have little self control and are unable to hold their tongues, are unable to come to rational conclusions to explain why they say what they do and in the end of the day they just do what daddy told them to do, and that's HATE him, HATE her, HATE that, HATE this.
Almost anyone, no matter how perfect you think you are can be singled out and attacked for what they are and who they are even when it's uncalled for, and I'm sure everyone can relate to this, even if you disagree with what I've been saying. The difference is you can either be as bad as them or better than them. Self control vs irrational critisizm justified by hate.
