Fine. Conservatives founded the United States. Then that means that Conservatives guaranteed slavery and Liberals detested it.
Really? That's interesting. I seem to recall that REPUBLICAN President Abraham Lincoln lead the effort to end slavery and the Demcorats vehemently opposed it (as they did again during the Civil Rights movement in the 1960's).
Abe Lincoln was a liberal. Liberals authored and passed the 1964 Civil Rights Act.
The following was copied from Wikipedia, pertaining to the passage of the 1964 Civil Rights Act. If you pay attention to the numbers you will find it (probably to your surprise) that in every category the Democrats were far more reluctant to pass it than the Republicans. (by percentage, since both House and Senate had Democratic majority).
Also you will see the name of a Democrat icon in a place that should be uncomfortable for any democrat with a smidgeon of decency.
