Not under the rule of Law.
A man is innocent until proved guilty.
If you want to prove someone is a racist, then the person making the accusation is the one who has the burden of proof.
I apologize for not stating that this was sarcasm. Everyone is being called a racist these days and I was merely joking that De Blasio turning his back on an Asian business owner “could” be construed as racist in the eyes of everyone who is offended these days.
