Do you even know what the Civil Rights Act was? It literally guarantees equal treatment under the law for everyone and forbids discrimination. It doesn't even make sense to claim that it "shouldn't apply" to other groups, the only way that you could keep it from applying to other groups would be to completely rewrite the law, and how would you write it?
KingofNYC proposes repealing the Civil Rights Act, and replacing it with a more narrowly written law that only forbids discrimination against straight black men who can prove descent from pre-1865 enslaved Americans.
Imagine a Tesla workplace meeting.
Elon: "Bradley, I just got word of another lawsuit. Three black employees are claiming that you called them racial slurs, paid them half what you paid other employees, and refused to promote them. What do you have to say for yourself?"
Bradley: "It's okay, boss, I did my research. Derek has a Dominican grandfather, Andre's family says they have Native blood, Reggie is a Hebrew Israelite and Terrance is a Muslim. We'll just claim that we were only discriminating against their non-ADOS characteristics."
Elon: "Way to go Bradley! Keep up the good work."
