Well, I can honestly say that I don't remember the Dixie Chicks thing, but I think I have good reason not to remember it.
However, from what I read...W was, in fact, the worst president America has ever had. And I think Trump gets that label because people like me are vocal but too young to remember things like torture, outing CIA agents because of their husband's articles, censoring the press, and opening offshore detention facilities.
CLEARLY there is a lot of hate in the GOP...
But I don't think I would call it the party of hate. At least not until everyone takes a nice long look into the mirror and acknowledges all the hate coming from your side as well.
