Incidentally - in all of my nearly seven decades on this planet, I have only witnessed an act of racism on two occasions in the UK. The first was some lowlife making vile comments to a black lady in a Netto queue and the other some Millwall FC yobs abusing a black officer on a police horse. (Averaging out to one piece of racism every 34.5 years! Yeah. Clearly rampant.)
Anyone who 'takes a knee' is adding approval to these assorted marxists and anarchists.
I do not doubt that there will be a goodly number of the terminally simple and people with extremely low IQs amongst their numbers, too!
