It should be discomforting. Because if it wasn't, we'd just continue down that same path. Guilt? Not unless you're continuing with that same mindset as they had.

We want to do better. We want to keep that stuff in the past and move forward. Not because we feel guilty, but because it was wrong and we want to do better. It should make you feel discomfort in the past. It was shit. Our ancestors (as a whole, not calling out my or anyone elses.) did some pretty bad shit. The best we can do is do better with who we can and with what we can.
