Instead of a lawsuit we should do something slightly different
In our country we need to systematically hold responsible the two leading parties for the things they do that are wrong. We should tell the people what the democrats have done and leave it at that.
The facts that every american should know about the politics of slavery/racism are as follows. The Democrat Party supported slavery very strongly before the civil war. The republican party was founded for the purpose of abolishing slavery. It may be true that republicans and democrats were equally likely pre civil war to engage in the ideology or idol of racism, but when it came to slavery as a political issue the democrats were 100% in favor while the republicans were 100% opposed to it. The civil war, costing 650,000 lives, the world's largest war up to its' time, was largely a war between republicans and democrats. The republicans won.
After the civil war the nation's first civil rights legislation protecting blacks was passed in 1868 by republicans.
The ku klux klan was started by democrats. Virtually 100% of members of ku klux klan in the first 25 years of the kkk's existence were democrats. Although it is true that in the 1920's the kkk reached its peak in membership and by then they had a very healthy republican contingent.
All of the Jim Crow laws were passed by democrats. I personally am under the impression that very few republicans even voted for that type of legislation.
Calvin Coolidge, the republican pres in 1920's, did publicly speak out against racism at the time and he did so in the deep south.
In the 1930's though the black people realized that the republicans were racists and so they started voting democrat in large numbers. The democrats promptly passed legislation that empowered the labor unions knowing full well that the labor unions were racist at the time. The labor unions took over many industries and wherever they took over in the 1930's they required an all white shop. Probably the largest trucking firm in the state of new york at the time was black owned and employed 98% black. It was run out of business by the unions.
In the early 1960's in 1 of the big civil rights votes 80% of republican senators voted for it while only 60% of dem senators did. In the house it was much more lopsided in that less than 50% of dems voted for it and republicans actually were the ones who turned the tide as a minority party working with a divided majority party.
Ronald Reagan was the son of relatively poor white people who literally taught him not to be a racist. Al Gore was the son of rich white people who set an opposite example.
The politician most known for campaigning against civil rights legislation during the 1960's and in favor of segregation in his state was George Wallace, a democrat. Who could forget George Wallace standing in the university of alabama's door to prevent black students from coming in as soldiers stood by and broadcast on tv across america? If you listened to Wallace' rhetoric in Alabama politics, then who could forget him bellowing 'Segreagation Now! Segreation Todeay!! And Segreation Tomorrow!!!" with so many white democrats cheering for him? Even after all that more black votes in alabama during wallace' entire 20 year career were cast for george wallace than against george wallace. Because everyone knows that republicans are racists.
The Democrats won the racist sweepstakes in the '30's, as they have before and since. I believe that blacks blamed Republicans for the Great Depression and went Democrat for that reason and because of all the promises of a Socialistic Paradise that the Left was making then.
