Before intersectional feminism aka cultural marxism ruined western women, it was mostly up to them to act as moderators to biological male impulses, to protect themselves from unwanted pregnancies and absentee fathers.
In other words, before women were allowed to enjoy sex as much as men.
And why do men who are serious about stopping abortions need someone else to moderate them? Why can't men, especially strong alpha men, control their own impulses?
The left who loves to brag about how much they respect mother nature and cherish science are proven hypocrites when it comes to natural patterns of human behavior. For thousands of years human society operated by a certain code ingrained in our very DNA and now all of a sudden we want to just throw all of that out the window. And you wonder why men are turning to drugs, suicide and violently lashing out at society?
Even the most conservative "alpha male" can be tempted by a decent looking, easy woman. Men are dumb like that. But really, it's the non-conservative men you need to worry about. The ones who have no intention of sticking around to support their kids, the ones who will encourage and intimidate that drunk teenage girl he impregnated at a party to have an abortion.
