THe motivatins of the Communists were not related to civil rights, The Democrats certainly did do a lot - and Democrats tried to prevent it.
However, it is not true that Republicans did nothing
Didn't say they did nothing, just that they did virtually nothing at the street level, nothing they got credit for.
No civil disobedience, no jail terms, no dog bites, no deaths. The right didn't put their bodies on the line, so the left gets all the credit.
I could be wrong, along with most of America that gets its news from the MSM.
