re: I'm proud and happy that this land, America, was conquered by European explorers

Since this is my birthday, I'll add my own endorsement to this principle.

I've often asked (relative to the slavery/systemic racism issue)
"pick any moment in time - and answer the question = "What would you have done instead?"

this applies doubly to the 'discovery of new world indigenous people' = what would you have done instead?

- and when they start with "don't destroy their culture" all you have to do is remind them of their toppling statues just this past year.

ANY morality-based 'sin' they come up with is exactly equivalent (if not exceeded) by the actions the progstains are rabidly pursuing today.
