Is legal marriage the only way to ensure commitment for a man? Wouldn't a "good woman" understand how the family court system is extremely biased against men when you present the evidence to her?
I'm gonna compare this to a fictional scenario I just made up. Let me know if this applies at all or not:
You go to a job interview. The job seems great, and you want to work there. Right before hiring you the employer wants you to sign a certain contract. You read it and it says that the company can fire you at any time, and is entitled to 40% of your earnings for 20 years after they fire you, if it is in any way dissatisfied with your job performance. They also might have the State seize your guns or lock you up if someone in the company perceives you as "dangerous". If you don't comply, you go to jail. After you tell the employer that you refuse to sign it, he says "Well, that proves to me that you're not serious about the job".
