I hate stereotypes, but sometimes they're true more often than not.
Most conservative men are jerks. Most conservative women are nice. Liberals are the opposite: Most liberal men are nice, and most liberal women are jerks. There's lots of exceptions but it's true more often than not. I assume people are like this. It's because of ME ME ME ME ME. Most liberals are feminists and most conservatives are for traditional gender roles. People who support themselves sound like jerks. People who support others sound nice.
I wrote before that most observant Christians are conservative and most others are liberal because the stereotypes cancel each other out. Gender throws another wrench into this. They don't come across neutral. They come across the way their gender does. What's sad is there's more jerk exceptions than nice exceptions. You find more jerk conservative women and jerk liberal men than you do nice conservative men or nice liberal women.
Politics play a bigger role than religion in how someone acts. Most left-wing Christians act more like left-wing secular people than conservative Christians. This always holds true. Most left-wing Christians swear and drink as much as their secular counterparts, even with conservative theology. I don't know enough right-wing secular people to know if they act like right-wing Christians. I don't know enough people in other religions to know how they act. From my experience, conservatives act conservative and liberals act liberal regardless of religion.
Once again libertarians don't fit into this.
