As soon as it becomes common for feminists to attack the manhaters in their midst, and manbashers get just as many boos from the crowd as womanhaters do, and no feminists dodge the question, make bullshot comments about the dictionary, or make excuses or babble about "irony," you'll be able to beat that stereotype.
But without that? Never.
There's a half-century track record of feminist behavior that MUST be addressed, pretending won't help, it won't just go away.
There's ALWAYS gonna be reactionaries who are against change and say bad things about those who want change, but fer cryin' out loud, don't you think fifty years of GIVING them something bad to say is ENOUGH???
