It would help if plenty if public services, government websites, and even large companies could actually sort out their certificates so it didn’t happen all the time on actual official websites.

Maybe banks could use a way to authenticate the user a second way, that doesn’t involve a password. If only. (Sidenote: why do banks still insist on sms 2FA?)

I wouldn’t call the argument a bad faith argument. Perhaps there is a line somewhere, but ultimately, his argument is that “two people who have an increased chance of passing on genetic disorders can’t have children/have a relationship”.

For most people, when asked this question outside of the incest framing, would argue that the state has no role to dictate that line. The slope is too slippery and screams too much like eugenics. It’s only within the social taboo of incest do people think that argument is acceptable.
