At least you recognize there 'are' two sides.
You can't put the toothpaste back in the tube. The slaves are free, women vote, segregation is against the law, gay's are out of the closet and fighting for legal rights.
Acceptance of change doesn't come without a painful period of growth. To have someone tell us that our poop stinks when it comes to Native Americans and Thanksgiving is just another thing that's hard to wrap one's head around- like how can people find teams like the Washington Redskins and Cleveland Indians and their mascot - offensive? Might be hard to understand unless it's your heritage being mocked.
How dare they mess with Thanksgiving!
