> we didnt have any of these guards in the 90s and early 2000s and everybody turned out just fine

One of the most highly valued tech companies of today makes a software that sometimes talks its user's into killing themselves. Some guy put "uwu notices bulge" on a bullet casing and shot Charlie Kirk: things turned out fine indeed.

People killed both themselves and others way before the internet even existed.

Requiring everyone to show their id on every website will not change that. It will limit free speech though.
