It is appalling that more people don't know and use this word to describe such a commonly encountered form of bigotry. "Misandronist" is also used, but far less often.
Thanks for pointing out the word. I was looking for something that was a little more satirical based on the word "homophobic," which actually means "fear of humanity" or "fear of mankind." Still, I appreciate having a synonym available for my admittedly make-believe word.
