Is there huge difference in USA if you are born white, black or brown?

If you are a straight white male you get remind by liberals, feminists, popular culture, and the news media just how much they hate you on a daily basis and everything that's wrong in the world is your fault.

You left out yellow, that's racist !

Of course. From birth to death. Are you watching the trial about George Floyd's killing?

in a probabilistic sense, yes.

otoh, you may be born rich, extremely good looking and/or talented, or intelligent & socially adept, etc., and those possible impediments become much less severe.

we don't like to think that the circumstances of our birth & upbringing, in terms of race or class, matter much. but they do, looking at the general picture.

how that should effect social policy is another matter. i'm more inclined to class & income based approaches to addressing social disparities, for a lot of obvious reasons.

Of course.

Yes:)

Let's be real, no one is really equal. We all have our biases.

Yes. As an example, a black person is 3.64 times more likely to be arrested for marijuana possession than a white person, even though black and white people use marijuana at similar rates.
