> required verifying that I was an adult

Log in to your account and toggle the “I want porn” option? It’s annoying, but not onerous.

> And I know for a fact that the UK has much stricter limits on kink and BDSM in adult content as well.

I know what you’re referring to, but don’t know the full details. I believe it’s around violent porn (rape, etc). We certainly have a “think of the children” brigade. I still think the discourse is significantly more civilised than that of the US, which feels like it’s approaching virtual civil war levels. When these subjects are debated, it's usually in parliament and doesn't turn into some societal ideological divide.

I think some of the policies you mention are more artefacts of the politicians not understanding the technological future we’re in, rather than ideology. Many of them think they can make the internet a safe space for kids through policy. It’s naive, for sure, but usually not dogmatic.

> What gives with people claiming it's just the US?

It’s not just the US, but when the people standing outside of UK abortion clinics harassing women are funded by US ‘pro life’ religious groups then you know there’s a problem. Puritanism is a US export.

The vitriolic political divisions in the US, which leads to all sorts of fringe issues becoming mainstream (trans rights, for example), is leaking out into the rest of the western democracies, poisoning the debate everywhere.

The Visa issue is just one more of these puritanical US exports.
