If we're being serious, my arguments are, look at the crowd. A bunch of at minimum privacy aware fringe (relative to big tech platforms). We consist of less than 10 women, most of which are married and a bunch of dudes probably in their mid to late 30s. If you have used any of the "fringe" but popular dating apps/websites you find one "woman" within 100 miles of you, if you move the range to include Washington DC and northern Virginia you get a few more "women". You have to build real trust, which means you must expose private information over an online system. I know I have a bias against dating apps (because they simply don't work for the majority of users) and people can't keep pointing to the 1/100 users that entered their first marriage at 23 that no one was invited to and are too socially awkward to leave their house.
