> the only reason you pay attention to sides is identify with and wanting to defend a side in the first place

True! For example, I inherently have a bias towards wanting LGBTQ people to have the right to participate in society through marriage, anti-discrimination laws, etc because I'm LGBTQ. I suspect a lot of black people have a bias towards wanting anti-discrimination legislation so they don't get discriminated against, too.

Does that strike you as unreasonable?
