Does this make the suffragette movement any less important? Does it make feminism any less valid? Does it make racism any less hurtful? This is an opportunity for growth and learning.
Of course you could be racist against whites, even if you are white. It is the actions that define what is racist or not. If you targeted whites for persecution based on the color of their skin, you'd be a racist. It is also highly racist to push white guilt on others, that sort of nonsense just proves whites can be racist towards whites...
sorry sunshine but i cannot be racist to my own race. maybe in your world that is possible but not in common sense land.
