You are essentially saying fascism does evil against minorities and that is the definition of fascism.

That's only one part of it, but it is one of the biggest. Really, I define fascism as silencing a group, idea, culture, or mindset.. typically through violence, intimidation, and-or doing the same through the abuse/corruption of establishment systems. So, I also include the tendency for those to try to intimidate or force others not to share ideas they disagree with.
