“Normal” = in accordance with the prevailing local culture.

This is rather what “critical race theory” is about. The rules of the larger American culture deem these behaviors as unacceptable, though they are completely “normal” within the subculture in question.
That is why the larger culture and the laws that extend from those mores are deemed “racist”, because the laws criminalize what is “normal” within the subculture.

Isn't this the same argument that the supporters of Sharia Law are making?

At one time this was termed the "Law of the Jungle" but that was during the unenlightened pre-rainforest days.
