Preferences vs principles

Most of my personal preferences, when I have a preference, could be described as "conservative".

I want to be able to carry guns everywhere I go without any "authority" having any say in it whatsoever.

I have no desire to use drugs without a real medical need.

I have no desire to marry a man, nor to have sex with one.

I know taxation is theft, and welfare is destructive.

I recognize that "affirmative action" is just racial or sexual discrimination codified by "law".

However, I know beyond a shadow of a doubt that making "laws" against non-aggressive consensual behavior by others is wrong. Actually "wrong" isn't a strong enough word. Not just "not nice" or "controlling", but absolutely, horribly evil. There is no excuse for it.
