I don't think they did so intentionally, or even out of cowardice.

There's nothing wrong with having cultural diversity in the 'inner city'. Lefties say that's preferred, righties say it ruins things.

They're nothing wrong with having cultural hegemony in suburbia. Lefties say it ruins things, righties say that's preferred.

They probably moved to suburbia for a quality of life and culture they wanted.

Those left in the inner city? They were supposed to work their way up and out, just like most everyone else. Sure there were a few rough types, some bad ombres. But why would John Q. Public veteran think his previous neighbors would turn into thugs demanding their gibs? John wasn't raised that way. He was raised to have self respect, and presumes most other people do to.

It was ignorance, not cowardice. If they knew then what they know now, they could have acted and things would be different. BUT immediately post WW2, how would they know?

Yes, there are solutions. And if they had been even more awake they could implemented those early solutions.

But don't insult an entire generation because of few dingbats, fuckwits, and leftists.
