The most powerful man in the House doesn't like divorce

This is very on brand for republicans. It is part of the overall plan to create Gilead (that SHOULD be an exaggeration but... if anything it is an understatement). The idea being that women are property.

1. Abortion is evil. Because if a guy knocks up a woman? Assuming he doesn't "deny deny deny" and his lawyer can't get him out of it, he is looking at a ridiculously small tax that he pays for a few months and then ignores for the rest of his life. A woman loses months (if not years) of her life to recovery and childcare and loses earning potential for her entire life. Which... makes her more beholden to her spouse.
2. Affirmative action is racist/sexit/whatever. Because, same as above, it makes it easier for Manly Men to refuse to promote or hire women to keep them barefoot and pregnant because they can't get a job.
3. Divorce is wrong: So even if your property gets uppety and thinks she can find a way to survive without you? Sorry, not legal, go cook dinner and then I'll put another baby in you.

And plenty of others. The goal is to make women property that can't escape or ever say no.

And the idea of a man wanting to leave a woman? Just kill the bitch and get a new wife. Or fuck your daughter.
