You need to look up what the word “nominally” means, it completely changes the meaning of the sentence you’re objecting to.

Not once do the words “never been” appear in that person’s comments. You’re arguing against something they didn’t say

My bad. I used a double negative, which clearly confused you.

“That doesn’t mean that racism doesn’t exist there” means “racist behaviour almost certainly still goes on there”.

I can try to break this down to words of just one sound if you like, but to do that might be too mean, and it’s hard to write like this as well.

Do you not know how to read?
