No, you dont have to embrace false religion in order to reject feminism and fight against it.
Show me a present-day Christian preacher who openly rejects feminism and declares that wives should submit to their husbands, and that a wife who divorces her husband other than for grave reasons is a sinner who should be shunned by fellow Christians.
And I'll show you a preacher with no women attending.
Modern day preachers understand that it is the wives who decide what church the family will attend, and tithe to.
