aog, there are plenty of racists, passive and active, among young people.
But it must follow, if it is accepted that racism was commoner in the past than now, that gradually there will come a time when more racists are old people. The young racists will have become old ones and have not been replaced in the younger population by an equal number of young racists.
Has that happened yet? It must be happening, if the premiss is sound.
Is there less racism than there was? Yes.
.An instance: I can remember being at Chelsea in the 80s when we got our first black players. The comments in the stands were racist and abusive. The first time I witnessed it, the player, possibly the first, hadn't played for the first team, and came on as a sub. He hadn't even touched the ball yet. As he ran out, a Chelsea fan said loudly and angrily "There's a f----- c--- [rhymes with 'moon'!] playing for Chelsea !" John Terry, if guilty, has done nothing like that! And nobody around that fan made any adverse comment at all. There was an easy acceptance of his saying it. There wouldn't be now.
