Multiple reasons. 1st and foremost is the freedom of expression and assembly, which the civil rights act blatantly violates. There’s also the fact that the act has never been held to the “equal” standards but has allowed the brazen racist insanity we see today where even US Colonels are allowed to say “Don’t hire white men” with zero repercussions. The only version of a civil rights act that should exist is one that prevents the government from discriminating against it’s citizens. Not one that openly allows racial, sexual, etc discrimination as long as you are not a “minority” or “protected class”.

I personally would like it not repealed mainly because I would be personally affected by said policy obviously

Doubtful, if anything you would see a massive boost in acceptance for not being a SoundCloud rapper with face tattoos. Sowell covered this quite explicitly and is something he is more than qualified to speak on being a black Harvard graduate before the CRA. He also goes over how most economic businesses would have “racial policies” that were rarely enforced (see the actual story of Rosa Parks) because it was completely economically unsustainable to have to run two passenger cars or buses for people that were all able to fit into one. The government were the ones who forced businesses hands on the matter and cost them massively financially, same with minimum wage, affirmative action, on and on.

The government should have no say in how I want to run a business, if I want to hire straight white men exclusively then I should be able to, the economy should be the decisive factor on whether or not that is sustainable or enough “diversity of thought” to compete with “diverse” businesses.
