Aspects of modern "morals" that don't make sense

[dazzn]

Anti-racism - IMO, slavery is normal and legitimate, and I suspect most believe this also (secretly).

No, I don't. Slavery causes unnecessary suffering and tends to lead to either you or your offspring being killed in an uprising. It is also not an economically superiour model for a society, so it has neither moral (which I assume you find relative) or economic value. It is also not normal in modern society, unless you live in a 3rd world country or the criminal underworld.

Anti-sexism - Who says it's wrong for a man to hit/physically strike a woman? Who defines this "wrong" beyond what society says?

No one, but if you are going to live in society you either follow its rules or your suffer its consequences. If you don't like that, move to a society that believes morality is relative or at least thinks what you find acceptable, acceptable.

However, I would argue that it is wrong and impractical, in that you cause unnecessary suffering and hatred, which leads to eventual consequences (divorce and having most your money taken, sending to jail for domestic violence/assault, the assaulted woman coming back and putting a knife to your throat after removing your balls... stuff like that) and has no practical use outside of self-defense.

Anti-classism - Look, the poor are where they are for a reason, since they lack the genetics to prosper.

You know nothing about economics, which seems to be unsurprising given your lack of understanding of moral principles, practical behaviour and action/reaction consequences.

So anything goes, I agree. And?
