All the various -isms are merely synonyms for envy. People always want something they don't or can't have for whatever reason. When you run out of non-confrontational arguments, you start hitting them below the belt with certain words but still, it's just jealousy, plain and simple. The only thing women can't handle, in my (ample) experiece is an another woman's success. The same goes for men. It's simple, but we prefer overthinking it.
