NO, an Executive Order (EO) cannot be easily overturned. An EO can only be overturned by your High Court if that EO is Unconstitutional ... you conveniently left that bit out, LOL!!!.
Now, I put it to YOU. Can you think of any mistreatment of AA's that is Unconstitutional?. If yes, how come there was no persistent outcry by the people that were affected the most. How come the only solution was/is to resort to violence by those affected the most and, how come that violence only erupts within our inner cities and not in hoods where the Black Elite and Black middle classes live. I'll answer that ... because no one gives a feck about the underclasses, this is class warfare.
YOU have criticised most of what I've said yet you haven't come up with a viable solution ... only the same ole boring arse cliches coupled with a defeatist attitude.
We are writing history as we speak. IMHO one can't just airbrush out the mistakes WE made as Black people in THIS current generation.
I was lucky to be brought up with two Parents ... so many youths to-day are not that lucky ... the only logical outcome of this is a TOTAL lack of respect.
