I hate the virtue signaling age gates on websites. If a kid's browsing habits aren't being monitored by their parents then you have no right to decide whether they can or cannot visit your website. And if a kid never gives away the fact that they are a kid, how are predators supposed to target them?

Websites should instead say "if you reveal or claim to be underage, we will ban you. Kids are allowed on our platform, but only so long as they maintain proper anonymity." And they should say "I never wanted this website to be viewed by kids. If you are a kid and you click through this warning then I am going to cry and piss my pants. [Exit]|[Continue]"
