2) What is this nonsense about group A and B? Are we responsible for our ancestors? Are you prepared to say everyone in group B is responsible for any and all harm they collectively do? The answer is no, you would elect to treat people as individuals instead, so it seems it's you that treat the different groups differently by assigning collectively responsibility to only one of them.
3) "can't see color" is absolutely the correct way forward. We've spent decades proving that what you look like has nothing to do with your talents, motivations, interests, passions and character. We will never progress forward if you continue to discriminate and treat people by the very characteristic you claim is being used to discriminate.
4) The system is nothing but laws. Anything else would be up to how a specific individual deals with those laws, which is a problem with that person and not the system.
5) Anecdotes are useless. The travel ban is not what you claim it was, but perhaps you should look at how members of that religion handle racism first. You won't find any multiculturalism there, that's for sure. As a foreign-born naturalized US citizen, I don't support birthright citizenship either. It's unique to only the US and Canada, not the norm, and repealing it would solve many problems.
6) I don't hate left-leaning American's. This is your projection, clouded by your bias and judgement. I only hate policies that enact the very discrimination they aim to solve, created by people who are ignorant in the problems they aim to fix while ignoring all consequences of those solutions and further blocking any potential discussion or feedback.
7) No, the modern left is not responsible for any of that. America is a melting pot and has been for centuries. This is not some new development, it existed for generations before you and there are no serious attempts to stop it. Again you keep using anecdotes to say a few people are representative of the whole. Is there a country without criminals? Does that mean we all commit crime? Clearly not, so why don't we look at what actually is the reality instead.
