Hmm, can't say I agree with "sissy" or "prissy" being demeaning to women. The concept is that you're a man acting like a woman. Is it an insult to men to say a woman is being "manly"? You're not saying being manly is a bad thing in itself.
Of course all the above stuff isn't good because it's judgemental etc, but I find them minor offenses,
depending on context. If you're calling someone a sissy because they're making a big deal out of having to clean a toilet, then yeah, they're being a sissy.
If you're calling them a sissy because they like art, then yeah, lame.
