I can never be our religion The polygamy would eventually destroy a nation, even if it was a white ethnostate because you would end up with millions of men without wives. While this is good for eugenics as the "alpha" males, or whatever non cringe word you want to call them will breed better children. But you end up with a lot of angry and sexually frustrated men. Increased vengeful attacks AND they would resort to homosexuality too. This is why Islam always needs war and expansion to keep increasing the ratio of females to males. If you did that in a white ethnostate you would have to go to war against other whites and even if you did that you'd run out eventually.
