I'm starting to come around to this idea of liberalism. For example, what if someone consensually wants to be a slave? Then perhaps we shouldn't criminalise slavery. Nothing should be illegal.

You have a bunch of people coming together dehumanising themselves behaving like animals and we're oppressing them still insisting on treating them like human beings.

I am thoroughly convinced at this point that the ban on machine guns is unconstitutional and wholly incompatible with the concept of liberty.
