The Crowd is not the sum of its parts.
You don't get to make an accusation, and then demand someone else prove you wrong, without supporting your accusations yourself.
This attitude that once an accusation of racism is made someone has to prove otherwise is absolute garbage, and the lowest of the low in forms of public debate.
A Canadian conservative is one who believes in limited government and that the government should stay out of our wallets and out of our bedrooms.
But racist, hell yes.
The south gets to be non-racist unless someone can prove that each individual person in the south was also racist? I think the burden of proof is slightly misplaced. "Prove everyone is" is better constructed as "Prove one isn't".
If you want to claim that the entire South didn't fight the war for racist reasons, you need to find one person who fought for the South for reasons other than slavery AND who also thought that either slavery was wrong or that blacks and whites should be equal. Moreover, this can't be just a soldier on the ground. This needs to be someone who's opinion mattered at the time. Obviously that's pretty much impossible as most northerners were also racist.
But this doesn't make the south worse than the north. After all, both the north and the south committed genocide against the Native Americans in the name of manifest destiny. All countries and peoples have "blemishes" in their past.
