Your argumentation makes sense.

I think that Liberalism itself will fail, though, because no bargain can be kept with the leftist elements, especially if they educate new revolutionaries against every status quo. This is a problem with revolutionaries and bargain-making as a response to them.

Civil Rights is something I agree with in principle because there isn't good moral warrant for the use of oppressive force on Racial grounds, but take issue with as a bargain struck with revolutionaries. The revolutionaries will absolutely continue agitating along different grounds while using our morality itself against us.

The reality is that the policing of anti-social behavior among Blacks continued to the Justice System in America after Civil Rights, with mixed results. I look at NYC halting 'stop and frisk' laws in much the same way: "So the old model's gone. Fine. Now we have more crime. What are we going to do about it?"

I also disagree here:

The host is simply not damaged by removing legislation that is racially targeting that group for sanction, and separating them out (rather than allowing them to integrate) from the host community.

Cultural integration cannot be assumed. A lack of integration is precisely the cancer afflicting the host.

The type of freedom we could agree on is only possible when the institutions of education are used for acculturation and immigration is kept low-- neither of which is happening in modern day America. The cultural and intellectual legacies which make the US individualist (and thus free) are being actively eroded.

Without integration the US's Rainbow future accelerates along the same course as South Africa's vibrant democracy, just at a slower velocity.
