If your point is that there have been racists in both parties, that's a valid point. However, the original article is, as you know, about "history."
The GOP was formed largely to end slavery. In contrast, as set forth, the founders of the Democrat party were were overt racists, supported slavery, and kept up that racist history well into the 1960s.
Both parties were content to let the status quo stand till the 1960's G-man. Plus the party redeemed itself in the 60's when the racist democrats fled to the GOP. I'm guessing that's not in the writer's agenda though nor in his history.
