Black ppl can’t get mad at white people if it was their own people who sold them as slaves 😂😂🤷🏽‍♀️

Perhaps, but ending slavery was still messy in America and even after that people still treated African Americans as inferiors with unequal rights and just blatant racism for around another century. When your own government discriminates against you with laws and regulations, I can kinda see why they'd be mad about it.
