I know this tweet is satirical, but people of either gender get angry when someone does something that they feel removes or negates their dominance in some area they’ve traditionally held it. Women control the dating space with an iron fist and when anyone impinges on that or obtains what they feel is an unwarranted advantage, they get extremely upset. It’s a natural human reaction. Men police other areas to a similar extent, though that’s been decreasing a bit in recent years.
At least 90% of the “feminist” reaction to the PUA community was not due to its misogyny but that PUA advice actually did cause (in their view) undesirable men to get markedly better at social interaction, which was a threat to PMC women.
