American conservatives have always had distaste for Europe due to its different mores, more liberal political center, and general diversity of cultures. And also the overall view that anyone that isn’t “us” is “them”

The same dumb stuff they did in the US.

Kids can access porn sites if unsupervised. So they blamed the porn sites for not properly age-verifying users. The only way to do that would be to force porn sites to check IDs. Porn site visitors want anonymity and are not going to enter their government ID on a porn site. So instead, those sites just block traffic from the states that passed the laws, and all the porn visitors either use a VPN to access the site anyway, or find an even shadier site to visit.
