I understand the point you're trying to make. However, I think a reasonable person would likely agree that just because something happened at a non-federal level, it's not the same as a national party being in favor of it.
But that' s not really the issue here, is it? So let's just agree that we view that differently, and get to the real issue.
What's really at issue is the fact that you want to dismiss the fact that it was democrats who were the party of slavery, and for what is a very legitimate reason imo, meaning it was long ago and the party as well as the times have changed.
Yet at the same time, you're trying to hang something that *some* republicans were involved with at a similar time, on republicans today. In particular, this looks to be just another example of petty, ineffective Trump bashing.
So which is it? Because you have to be consistent... right? Either we hold both parties accountable for their actions in the 1860's, or we hol neither.
Well, if you're a liberal, there's no requirement for intellectual consistency, nor honesty, so maybe that's a waste of my time to try to hold you to that concept.
