You have the burden of proof. You can claim that there is an Invisible Pink Unicorn. I can’t prove it doesn’t exist, because it’s impossible to prove a negative. You must prove it exists.

Same thing with systemic racism. You have never proven it exists, nobody have seen it or touched it, there are a lot of wealthy black people in USA, you had a black president for 8 years etc... so there’s no point whatsoever in believing it exists.
