With the fourth of July being just yesterday, many people have been discussing how we stole this land out from under natives. If I remember correctly, natives tended to always raid and steal from each other as well, this was a normal occurrence around this time around the globe, but the second we came in and took over, killing many yes, but also supplying superior technology to a lacking populace. Anyways that's what I thought happened but I am not to sure I have any of that correctly. I've tried to do my research but everything seems so biased. My question is am I correct? And is it as complex as I think it to be or are we outright villains in the story?

P.S. I have no source backing for any of that outside of random things I picked up over time. As such I'm very open to the idea of being completly incorrect.
