How about you get over that no matter how much you spew your twisted rhetoric that people are just going to forget and get over it? Would you tell that to black people who were wronged in the past to just get over it. No matter someone's race or political beliefs or any identifier, when people are being oppressed it creates anger. Whether it's fair or not, there are going to be anger and it comes with problems for the oppressor.
You can say conspiracy theorist, racist or whatever you want to dehumanize someone but you will only instill distain and you will isolate yourself and become a pariah, just like the racist of the past. Obsolete and hated and then in your own group all you have left is to tear each other apart. If you want a real life example, all you have to do is go to Politics Too.
