The Saudis could become the high tech center of the world. All they would have to do is create an enclave where Western tech men are welcomed to immigrate, and which they would guarantee would remain free of feminism. Import some attractive women from the poorer regions of the world, and men would flock there.
There may come a point where Western men embrace Islam, as their only defense against feminism.
No, you dont have to embrace false religion in order to reject feminism and fight against it.
