When present day oppression is justified and modern day genocide is ignored, the people who are responsible will likely continue those behaviors rather than be accountable for them.
I understand you don't want to be accountable for halting genocide. Just remember, you chose to ignore the treaties. You chose to obey unjust laws. The option to be a good person is yours. But my guess is that instead of choosing righteousness you will perpetuate injustice. Because you refuse to learn from the past.
No one is committing genocide in the US today so just stop it. You want to see genocide, look at what is going on in South Africa, Rwanda, etc. You are inflaming hostility for no reason. I didn't make any treaty with you. I didn't kill anyone and I'm not the one being hateful and racist here. You are. If you wonder why you perceive others as having an attitude towards you, perhaps you should look in the mirror and try to tone down your hostility towards an entire group of people who have literally done nothing to wrong you, yet you treat as if they have.
