Like how some people take offense and get "fitin mad" when someone badmouths the Confederacy some of their ancestors died and fought for.
The Confederacy was a traitorous group that tried to perpetuate crimes against humanity and refused to evolve in a new moral age. They were on the wrong side of history.
The Confederacy fought for the right to continue to hold human beings in bondage and treat them like property for their economic benefit. Raping, breeding, and treating an entire class of people like cattle for economic gain is about as close to evil as you can get without a Swastika on your flag.
Just because your ancestors were on the wrong side of history doesn't mean I need to feel all weepy because others can't understand why the Confederate flag warms your heart.
There are many flags throughout history that were on the side of evil and tyranny, the Confederate flag is little different. And if we forget that or try to glorify it, then if we aren't careful our American flag won't be much different
That's nice.
Does it change the treasonous acts?
Context is everything. America's succession from Britain is defensible and easily arguable from a moral point of view. The Crown was unfair and unjust in their rule of the Colonies. America initially tried negotiation and moral arguments for fair treatment and was denied and oppressed.
Between that and actually winning the war, America (in terms of its fight with Britain) has the moral high ground.
The same can NOT be said about the Confederacy.
I feel much the same way about someone who would get violent over something that happened before their grandparents were born..
If what happened to your grandparents and their grandparents still impacts your life today, then it is still relevant today...
...Should the people whose ancestors were raped and murdered by the Mongols keep hating them?.
If the Mongols' actions today are similar or a result of those aspects that enabled that rape and murder then yes....
...Should the Europeans hate the Christians because they wiped out their pagan religious practices?.
If the Christians still act in a way that threatens or harms other religious practices then yes.
...At some point the hate has to end.
At some point understanding needs to begin. The attitude of "get over it" is easy to say when you aren't the oppressed or when your life isn't negatively impacted by the historically events
