What's your opinion of the people that opposed integrated schools in the 1970s?

They were right.

It's understandable.  

It was probably mostly Whites who opposed it, I'd imagine, because they know they're much better off when left alone. But, of course, non-Whites know they'd be left behind, in the dirt, literally in many cases, if they didn't leech onto Whites and demand access to everything they've created - and so 'integrated schools' was a must for them.

Inbreds.
