It is because their leaders are all male chauvinist pigs, just as their idol Paul. Most of this hatred for women comes from that scumbag Paul, who reduce women to slaves. Paul also taught that homosexuality, between consenting parties, is a major sin and that fornication is the end of the world. Yet, they worship this "imperfect human"--seems they view all people as imperfect except the fictitious Jesus. Yet, they claim to not engage in idolatry?
And what about their other idol? You know, Tyrant David? That thing that never saw a Gentile it did not want dead? That thing would defend its enemies, as long as such were from within Israel, yet any Gentiles are not supposed to have any right to live. Proud of killing tens of thousands of innnocent Gentile foreigners, this monster is idolized by the Washtowel Babble and Crap Slaveholdery. Again, where is their allegience to their own rule against idolatry? Why disfellowship people for celebrating Christmas on the grounds of worshiping the sun? How many women-hating teachings did the sun spawn? How much hate speech against everyone on the grounds of not worshiping its own god did the sun generate, backed by slaughtering people for not worshiping that thing?
To compare, Satan has many Demonesses. Astaroth is one of the top Demons--female. Go figure.
