I'm not fully across CRT it's funny that this has been brought up because I asked about CRT recently in the man cave because some people have been bringing it up in my country and I didn't know what it was. It sounded odd and didn't make much sense.
I can't comment on CRT or the link between this post and it or what you're trying to align to. But I would be in agreement with you that current America was born in 1776.
Has racism occured it is a belief that is held by the weak to retain control and profit. There is more slavery today then in the past and we still all profit off it. Dalit caste of India are used as Slaves.
Are there still prejudices today yeah, because people are dumb. But not everyone holds that belief. Over 80% of people voted in favour of stopping slave Labour. If everyone was racist we wouldn't have abolished slavery.
