I never said it was only a UK problem. Of course, governments everywhere are trying to control the internet and some already have.
You could argue about those things, but I don't think porn is really the same. All those things apart from the watershed involve the child actually doing something that could be harmful to them, and with the watershed, parents are partially responsible for that because it's up to them to get their kids to bed before 9PM. With porn, it's just watching the sexual act, and in this day and age, the majority of children are introduced to 'real' sex by porn. I think children sort of know when they're ready to view things like that anyway, because they start looking for it; I know I did. Children don't typically search for sexually explicit material unless they want to see it. If a child doesn't want to see that kind of stuff, they won't look for it or they look away if it comes on spontaneously. Of course there are things like explicit ads popping up but things like that are solved by adblockers. Ime explicit adds usually only come up on dodgy streaming sites and porn sites themselves.
And yes, I'm well aware that most parents aren't as tech-savvy as their children. That's one of the things that make it sound like a not too bad idea. The trouble comes from the conservatives' motives. They have a history of being against porn and back in 2015 I believe, they outlined certain kinds of porn that they wanted to ban entirely. It never came to fruition but clearly the idea was still there. Then back in 2017 we have all the hate speech ******** laws that started targeting people for either stupid throwaway comments or genuine opinions. Restricting porn is just the next step to control of the internet. It's an easy way to build their base of external website blockers. After that, all they have to do is add new websites they don't like- I mean pose a threat to the public to their blocker. Trust me, there will be more categories of websites they ban. Next will probably be things like 4chan and liveleak. After that, they'll try and make it look like twitter and facebook are full of far-right scumbags or whatever and get rid of them, or turn them into a leftservative zombie form of it's current self. After that, they'll start targeting websites that routinely disagree with them, making them look extremist. This will continue until the UK internet is completely government-run and a lot of foreign websites are completely blocked (they won't go as far as NK as that would cause civil war as well as cyber war).
That is of course if they are voted back in in 2022 and 2027. Considering how bad Corbyn and SNP are (Ian Blackford is my new political enemy), and how little power the Lib Dems have, they probably will. Our country is run by complete idiots.
