"One is that there are quite a few people on the left in the UK who are in fact OK with positive discrimination and argue for it, and often think it is legal like the US, and that muddies the waters. That might be fixed with just better education."
It's not everyone on the left. I agree it is some (Stonewall, Good Law Project) but also sometimes people's positions are misrepresented.
However, while I completely agree better education would help... I am 100% certain that the solution is NOT actually making it legal like it is the US. Which is what abolishing legislation like the Equality Act would do.
It's absolute madness when you think about it "some people on the left think it's legal to discriminate based on sex/race etc. They are woke. Laws making it illegal to discriminate like that are also woke. Therefore we should get rid of the laws making it illegal"
I know that's not your position. It seems to be the logic behind Reform getting rid of the act.
