The ant-fa (anti fascists) started out as right wing fanatics and
became so radical they moved so far right they came back as leftwingers
and completed the circle to mimic Hitler's Brown shirts.
So the ant-fa are fascists which is why they act like Brown shirts.
It has been suggested that the rate of criminality of blacks is
reflected in riots. The odd thing though is the high number of whites
in the demonstrations. It might be like here where some are almost
white yet they never have any "white" attitudes. It is fashionable.

Re slavery the Africans were the "recruiters" of slaves for thousands
of years.
The Arabs were the trade managers and middle men for the Romans.
With the invention of the steam engine slaves became too expensive
and the British led the way in banning slavery.
There is a lot more in history in that vein.

When the unarmed Australian Justine Lamont was gunned down by African Police officer Noor two years ago I don't seem to recall riots by non-Africans in the streets of US Cities ?

ttbn, you have no sympathy for George Floyd, or the tens of thousands of African Americans who have previously died at the hands of racists using a system designed to suppress a people from the very start. It began with the savage, brutal, often murderous exploration of black slaves in the American colonies. The state sanctioned brutality of police forces, America has 18,000 of them, towards people of colour continues to this day, it has never stopped. Hand in hand with the injustice of physical violence, goes economic oppression of the same people.

You may say "While the murderous cop who quite inhumanly put his boot on that man's neck deserves to spend the rest of his life in jail, as do his colleagues who stood by" said without sincerity. Like the good white racists apologist you are, you find reason for the needed actions of the white coppers, its all this "black racism, which is always lurking, waiting for an excuse to run amok and do a spot of looting." Look up what an apologist is, because you are the one trying to justify the actions of the white coppers with false argument. Then there is a another of your "What ifs" this nonsense; "Had the victim of police brutality been white, (HE WAS NOT) there would have been none of the mayhem that is now occurring. White Americans do not behave in that way, (MANY OF THE MINORITY VIOLENT BURNERS AND LOOTER WERE WHITE) as white people don't worldwide (RUBBISH). Just one of the many differences between the races that renegade whites deny in their obsession with false racial equivalence." Your obsession with white superiority is on the record. As a once admitted member of a far right Australian political party, now defunct, your forum attitude to people of colour is evident. Maybe you have joined another ratbag party from the far right, and are not saying this time.

//the population of the US is in excess of the 1919 figure of 328.2 million.//

Well if they had that many in 1919, by now they should be near a billion or so, right?

seriously, not hard to find US population 1919.
