As someone who heils from a country whose government has been trying to ban internet porn for years and tries to distract its citizens with non-issues while trying to pass bills without anyone knowing, and said country is stereotyped for being sexually repressed, I can tell you that if porn is targeted by politicians, the public often tells them to go fuck themselves and they will back down.
They always try to use children as leverage for the bullshit reasoning. That was one of the reasons cited
for the UK to try and block porn, and their "solution" was requiring real personal details to verify your age. A huge privacy concern and an obviously blatent attempt to get information on its populace. Short-sighted, ridiculous, unrealistic, benefits no-one, and any potential for privacy leaks is always bad. After news spread and more people became aware of it, the bill was shelved.
I hate the arguement "think of the children"
1) There's laws against that, especially concerning porn
2) I will not tolerate content I view being taken from me because someone's little shit of a child gets off to tentacle rape hentai on XNXX.
Teach them proper sex education so they don't have to try and teach themselves, or let them do whatever as long as they're not being groomed. If they're curious there's no stopping it. Don't make everyone else suffer for it.
