We hear a lot about systemic racism and nobody doubts that the American people and justice system were once heavily weighted in favor of whites of European extraction, especially Englishmen, but that hasn't been the case for decades now. The plain and obvious truth to anyone who has spent any time outside of the USA is that Americans are among the least racist people on the planet, and anyone who has been in the corporate job market for long knows that if there is any institutional racism remaining, then it is against whites, not blacks. If anyone is likely to be the target of a racist hate crime, it's far more likely to be a white person in a black neighborhood than the other way around. I have never in my life picked a fight with a black person (or "African American" if you prefer), but I was attacked by black people in my own neighborhood many times in my youth.
99.9% of the time, if you obey the law and cooperate with law enforcement in the USA, you will have no problems with them no matter what your race or skin tone might be. When someone is shot or roughed up by a cop, in almost every single case, they could have avoided trouble by not *being* trouble. That doesn't mean that it's always right to cooperate with law enforcement nor that you won't be one of the rare exceptions, but it is a very good reason to obey the law and to be as polite and respectful as possible to all law enforcement officers.
Anyone who needs to be told that "black lives matter" will never believe it no matter how many times they are told, but the message of rioting, looting, & destroying lives will engrave itself in their hearts & minds forever.
Nobody who is countering with "all lives matter" believes that black lives don't matter. NOBODY.
But if BLM terrorists (if you don't like that term, take it up with the many dictionary publishers) are allowed to continue employing violence and threats as a political tool and if people keep accusing normal, decent people of being evil racists for believing that "all lives matter", then those normal, decent people will start changing their minds. Very soon they will stop believing that all lives matter.
And in a very real sense, they will be right because terrorists, murderers, human traffickers, and traitors to their people have forfeit the right to live. Mercy and forgiveness for the penitent is ideal, but eventually we're going to have to take decisive and unpleasant action to restore order and peace.
