Steve Shaw makes the point that you can't legislate morality but some bad laws impose
it on others.

Abortion is like Prohibition. Once you ban it, it will be rampant.

Drugs are a big business precisely because they are banned by law.

So don't try to ban religion or atheism unless you support a civil war.

Banning pornography makes it more alluring to porn addicts.

If you want a lot of people to read a book, ban it. (Salman Rushdie for ex.)
