Why is it not weird that tons of people use digital buffets to rate potential mates in their area before matching and meeting (often for one night stands)? Is that much different?
What about people looking for "the one" and going to unrelated social gatherings with strangers with that passive desire in the back of their head? That doesn't seem all that weird to me.
What makes this feel weird just seems to boil down to "they are trying too hard" or "they are trying in an unconventional way". The post said it: there are no unwanted advances, there is no harassment, there's just young men trying to find a wife, and pursuing that in a pretty direct and unconventional way.
