"Who am I to say rape and slavery are wrong?"

[Anomalocaris]

‘who am I to say slavery and rape are wrong?’

So I guess the ball is in your court. Prove that rape and slavery are wrong.

I don't give a rat's ass if they are deemed right wrong or not, much less whether you could prove it is right or wrong. I am satisfied that any efforts on your part to advance your self interest will appear to most observers to have turn out very badly if you act as if they are right.
