The "Progressives" are the ones who always try to inject race into an issues where race was never an issue in the first place.
This is one of their standard tactics from their bag of tricks.
This is one of the right's standard talking point attacks. If you can't defend racist policies, attack the left for being too much against them.
The right has never really stood againast blacks. They've just been for states' right, for tradition, for respecting majority, for not rushing change, for law & order against those radical potestors.
When the Democrats forced the issue to make them really be for segregation or against it, a good majority did vote against it. amd the battle shifted to assistance programs.
Not that they're 'against' blacks.
It's just the programs are bad for people. It's just we can't afford them. It's only that there are principles of this or that involved. It's just they're against reverse discrimination.
It's almost as if the conservatives' 'respectable' call for not addressing wrongs was part of a campaign to get elected by giving the majority what they want: excuses not to addess problems.
Remember my old sig quote:
"The modern conservative is engaged in one of man's oldest exercises in moral philosophy; that is, the search for a superior moral justification for selfishness." -- John Kenneth Galbraith
Once you understand that, it's easy to understand why attacking progressives for being 'excessive' on race is a popular line. If they're doing too much, then you are not wrong for attacking them.
Once, the 'liberal/conservative' divide was whether you beat your slaves more or less. Ending slavery was 'radical'. Then it was social equality - when Theodore Roosevelt let a black man visit the White House the nation was furious. You're going too fast with all this change, JFK and LBJ. There's a reason Martin Luther King, Jr. said "Justice delayed is justice denied" - because no one was 'against' change - but slow. It's those progressives' fault! Stirring up trouble with their protests against segregation, it's their own fault. Out holding signs that made people mad, it's their fault.
They're the ones causing the problems, injecting race issues where there aren't any. Why, most blacks aren't out protesting for ending segregation - it's these progressives making a problem.
