Fuck these prudes. It's time to stop accepting the demonization of sex by religious extremists. If we don't fight for our rights we forfeit them.
ISPs should do a better job at completely blocking porn access. It's poorly implemented in the UK.
If you want to block porn in your own home, there's plenty of consumer gear out there that allows you to do just that. Why do you want to voluntarily expand power of the government to moderate content that you're allowed to access?
I don't like national firewalls either but we're already here and have been for 10+ years, ie piracy sites.
But at least piracy has been solved /s
