Lastly, on Sexuality

I am heterosexual, but I loathe homophobes.

Discrimination, for the most part, is quite bad. In this case it is especially bad. Like religion, a person's views on certain things (politics, sexuality, etc) are largely determined by their parent's views. That doesn't mean that they can't change, it just means that they start off as right wing Christians who don't believe that it's moral to be a homosexual.

People's lives are ruined just because they find they love people of the same gender as themselves and it's the fault of heterosexuals who have no idea that these people are people. It's the fault of the people who think that they are the better ones, and sadly, it's not even surprising that it happens. Humans have to have something below them. Usually, they pick other humans. It's quite sad.

So don't pick other humans to be your punching bag (whether it's physical or simply verbal). Let those people who have no choice in the matter be the way they are. It hurts very few (usually no one, but there's always small cases) and it's not something that really matters.

The same goes for discrimination based on other traits. I'm not saying that it's amoral - I don't believe that morals are sensible or worth anything in the first place. When you discriminate against people, you just show how closed-minded and ridiculous you, as a "person", are.
