Birth control hormones are unnatural and nation-wrecking. They have some body-regulatory aspects, however it comes at the extreme trade-off of destabilizing women's bodies in worse ways which have major societal negative ramifications. And I don't just mean the insane evolutionary wrench that unlimited promiscuous sex brings in the break down of family and the allowance for a rise in hyper-feminist infrastructures backed by glorifying antinatalism, nor the chaos it all sows at the national security level: women are disposed to letting barbarians into the gate while the men around them are "replaced", therefore, it follows, more matriarchal influence leads to a weakened state primed for national genocide or autogenocide.
