Earlier quoted context omitted.
I don't think that taking a class to get to know single women of your own age is disrespectful. Do we know they are objectifying? The post said this was about finding a future wife.
It’s disrespectful because it ignores the fact that the women are not there to date, but to learn. The men are getting in their way by showing off and offering disingenuous tutoring.
Should men not seek dates? Should men not go where single women are to seek dates? Should men limit their efforts at getting dates only to "appropriate venues", where women's interest is explicit? How does the man's attractiveness factor into these constraints?
None of this seems reasonable at first blush. Obviously women don't want men they're not attracted to to engage them with romantic interests. Conversely, women generally do want men they are attracted to demonstrate romantic interests, regardless of venue (to a certain extent). But how can this constraint possibly be enforced in a reasonable way?
