Technically couldn’t it be argued that the confederacy were the ones that were the real USA? Even the constitution agreed with them that some people are worth less than others.
If you need to change the constitution to have your side be right, you’re on the right side of history, but you’re not the same country. You’re the new guys who took the country by force from the previous guys, because you didn’t like how they did things. It’s a good thing you did, but let’s not pretend like they were the traitors - the winners of the war were the traitors.
I just think it’s okay to be a traitor if you’re betraying a shitty cause, and by acting like it’s not okay, we’re just enforcing the “snitches get stitches” and “loyalty instead of morals” mentality. Which I get why you would want to do as a country, because you’re trying to keep the power and not raise future traitors to your questionable policies. But I don’t get why you’d want to do this as a human, who will be at one point in time responsible for making a similar decision. You’re just making it worse for future you if you’ll ever need to be labeled as a traitor for, eg: fighting to remove gerrymandering.
