As a non-Christian citizen who believe his gay friends should be treated as full citizens and fully human, I can't support Republicans.
You never did answer whether I have to follow the right deity to be covered by "all men are created equal."
Consider the following thought experiment: what if every Black person in America hated me? Truth is, It wouldn't make that much difference in my life. As a largely powerless minority they don't have much hold over me.
On the other hand, minorites are at the mercy of the system. They can't defend themselves. White racism makes a real difference in Black people's lives.
The point is that everyone has bias, but not all "racism" is created equal.
