Well, I've been meaning to write this for awhile - every day I am reminded by spellcheck that 'misandry' is not a proper word I should be using & wouldn't I like to pick another? Or, as the feminists would have it, "There’s No Such Thing as Misandry; its a modern, made-up word that makes you look stupid. and its as misogynist as fuck, so stop using it." (That's an actual, genuine quote, by the way, from the feminist website Femonade, Aug. 30, 2009).
Putting aside the curious logic displayed there - ALL words are made-up after all, they don't just come into being by themselves - the excellent research done by St Estephe over at The Unknown History Of Misandry shows that this is simply not the case: there are examples he provides in English as far back as the 1880s, & one in German from 1803. Here's one from a book review in 1871:
“We cannot, indeed, term her an absolute misandrist, as she fully admits the possibility, in most cases at least, of the reclamation of men from their naturally vicious and selfish state, though at the cost of so much trouble and vexation of spirit to women, that it is not quite clear whether she does not regard their existence as at best a mitigated evil.” [From review of novel “Blanche Seymour” (anonymous), The Spectator, London, Apr. 1, 1871, p. 359]It's a long, exhaustive but fascinating read, much like the site itself, & I recommend you go over there & give them both a deeper look. In the meantime I will just post a few of the clippings he has on display:
