Has somebody in this thread pulled "from numerous resources - specifically feminist social media" examples of notable feminists labeling men as pigs and brutes? If so, I missed it. We've got a total of one legitimate, card-carrying lunatic who was never influential presented as evidence thus far, and a bunch of cherry picked quotes taken put of context, many of which are from fictional novels.
This site is social media - can you find me some of this ubiquitous man-hating by feminists here? How about Dust1n? Is he always banging on about how all men are pigs and brutes? Mystic? Me? Sunstone?
This site is positively rotten with die-hard feminists. Have you ever heard anyone here say all men are pigs and brutes, with the possible exception of Muslim men trying to justify why their uncontrollable sexual feelings require that women be stuck into a shapeless sack to protect themselves?
If it's as common as you claim, you should have no trouble finding at least one example on RF.
RF in general is a pretty open-minded group. Just like how all the anti-feminists or non-feminists that participate in the discussion aren't misogynists even though you can find websites that champion male superiority. Or, if you want to pull from alternative discussions, we have virtually no anti-Zionists on RF that are also anti-semites.
That doesn't negate the fact there are misogynists, anti-semites, and yes, misandrists.
In certain Muslim and African countries where patriarchy clear does exist and it is brutal towards women, that society is completely eroded due to warped power structures in general - usually through war and international sabotage. The cultural influence seeps out in small subcultures but it is not in any shape or form a significant sentiment in the United States, Canada, Australia, NZ, Singapore, Ireland, or Britain.
