While you have a right to post whatever you want, it has to confirm to the standards this forum has in place. Libertarians don't believe in anarchy. If someone posted hardcore porn, that would also not meet with the requirements of the forum and would be deleted. You don't just get to do whatever you do.
Why the hell would someone post porn on a trading site? Plenty of great sites for that.
Stop saying you are Libertarian. You are not.
Allowing one person to kill another for convenience is not libertarian. I would look at some of your old posts to find other examples of the fraud you are, but its not really worth the time.
I believe in protection of the individual, you don't.
