When you phrase the question in such a way where people presume it will only target pornographic sites.

If you asked them would they support the law if it happens to accidentally block useful sites that have ZERO pornography on them, I'm very sure, the results would be very different.

Polling for the question “websites that may contain pornographic material”

Which is my point. The OSA isn’t popular as a broad piece of legislation, but the “think of the children” aspect that something needs to be done to restrict access to pornography is popular.

Watch the YouTube link I sent to better understand my point.

Personally, I think even the pornography aspect is stupid. If the government couldn’t stop me accessing porn when I was a kid back before the web was invented, then they’re shit out of luck stopping kids these days. The problem isn’t the law, the problem is parents want a way to diminish their own responsibility. It’s the same tired bullshit we see time and time again of blaming everyone else rather than making ourselves accountable.
