Just because one was the victim in the past, does not mean one is not the perpetrators today. This just further indicates that you should have taken the time to listen to what someone might have to say, rather than strawmanning.
Of course that's true that they could no longer be the victim, but that's not the case here. Woman still are treated unequally many ways in society, and white people are still privelaged over black people (for example) in society. There's plenty of facts and statistics to back both of those statements up. Look at the wage gap between men and women and the average wealth of black vs white families, for a couple of examples.

These are correlations not causations. But their truth values are, ultimately, completely irrelevant to the point being made, which is that you yourself have no desire to 'listen', but rather are attempting to simply have your quasi-religious propaganda imposed on anyone who disagrees with you, under the guise of rationality.
