That one woman made a good point: this is colonialism, which makes it understandable that teh USA and western Europe are supporting it.

Colonists landed in occupied land, expressed "surprise" when the natives attempted to repel them and used that to justify genociding most of them and putting the rest in tightly controlled camps.

I don't want to hear anymore about how horrible "Columbus Day" is. You're seeing colonialism live right now and giving it full support.
