Not arguing that it isn't better. I'm arguing laws don't always change things, and it probably isn't as good as you think it is (unless you live in a south deep-red place and know first hand, I'll take your word for it over what I've read). Actually, I'd argue that they rarely have the impact we'd like. I'd argue a lot of Jim Crow still exists, even though it is illegal.
Things are far from perfect today, but the current situation is a huge improvement. Informal segregation persists but it’s a lot better than the formal kind. Slavery persists in prisons but the vast majority of slave descendants are free. I haven’t seen any “colored” sections on the train lately, or “colored” bathrooms or water fountains.
