Let's redirect this a bit. What would be the necessary changes to be made to the marriage institution before it became a viable option for men again?

Whisper, in the linked post basically tells us- we need to get back to the original contract. That is-

1. to have and to hold from this day forth

2. Forsaking all others.

"Having" means fucking.

Basically all MRP does is say: If you women are not going to live up to the 1st term in the stated contract, then we men are not going to live up to the 2nd term.

A better option would be to begin FORCING women to live up to their promise in the contract. The first thing that MUST go is not unfair custody laws but a modification of marital rape laws. I agree a man should not be permitted by law to throw his struggling bride down and take her like a cave man while she screams and cries. He shouldn't have to. The terms of the contract are clear that he can TELL her to go to the bedroom and take off her clothes. She doesn't get to use sexual denial as a tool to seize control of the relationship and that is exactly what has happened.

"Marriage" does not even exist any more. Instead it is a corrupted, hybrid institution to funnel money from men to women and children while men are not even entitled to sex with their own wives. What the fuck kind of Bizarro world do we live in?
