The UK porn block and the concept of obscenity

I made a passing reference the to the UK’s new plan to block all porn but I decided that it, and obscenity in general, required a more thorough examination. In short, David Cameron feels that UK internet service providers need to block all porn by default to protect children. In short, again, that idea is stupid. It’s stupid partially because it will not work and partially because the mindset behind it is one that should not be accepted.
