Basically they're protecting the legally "protected classes" but as usual it's legal open season on white and Asian straight cis males, who fit into no protected category.

But any cis male can re-classify as a trans female (I don't believe any hormones or operation are required, just whatever you say) and thereby fall into a protected class -- guaranteed according to the SCOTUS decision of a couple weeks ago. (Thank Gorsuch for joining the "liberals" and making this choice available -- I am not entirely kidding here.)
