I don't know what your standards are in terms of someone looking like "someone you'd want to marry" are, but if you think that the amount of depth most people want in a relationship with their partner is something that a non-trivial number of people could fake over a multiple year relationship, you're wildly off base. You're either grossly underestimating the degree of emotional connection that some people (including myself) would require for a long-term relationship or you're grossly overestimating the proportion of the dating pool who are highly skilled, manipulative sociopaths willing to spend years on con with a high risk of no payoff.
its not about fixating 50% into the bucket. its about incentives. there are plenty of good women for sure. the issue is there's a lot of predators out there too. And they will look and act like someone you'd want to marry. right up till its too late. You want to deny that most divorces are initiated by women? that women get custody (and the house) most of the time and that family courts are incentivized to do so because they GET A CUT? fine. But don't lecture me like I'm somehow being a less than moral person for pointing out the very obvious hazard.
If you meet the right person, go ahead and get married. but don't go in without knowing that its a one sided agreement that doesn't benefit men in the slightest.
