Is the importation from America of Identity politics a good thing?

Other experiences and attitudes are available.

It depends where you were. Just because you lived in a cool diverse place doesn't mean that everyone did, in fact you're probably in a small minority. So when you say "I cannot understand the far left and all this woke, a lot of white people calling people racists. We didn't know what racist was" is great for you, but others had to have different approaches because their experiences were a lot different. For instance I watched a black footballer eat a banana that was thrown at him during a game here in the North in the 80s. I'm guessing it probably wasn't that cool an experience for him. It required people like me to continually say to ordinary folk "you know thats racist, you really shouldnt do that" to get it to stop. Then 40 years later apparently that attitude is "woke" whatever that means. I think it means being nice to people who are different, in which case I'm happy to have that label, or whatever new labels are invented to mean the same thing.

Yes. However your approach doesn't take into account when people were targeted precisely because they were different in some way, and simply being nice to everyone didn't improve things. People had to be actively shown that being nasty to someone because of skin colour just wasn't right. It had to be a proactive action.

Yes - Apologies, I meant to put an eg in front of skin colour.
