Liberty to me are basic rights. Rights are subjective, but certainly to me this means.
- Free Speech, Freedom of religion. Freedom of expression.
- Freedom to marry whom you choose or not to marry.
- Freedom for two or more consenting adults (or I suppose one consenting adult by himself) to express their sexuality in any way they choose.
I would include the right to buy and sell sex, but not the right to have sex with children. I suppose it includes gun rights (but I don't really care).
I am OK with liberty being subjective... but it has to mean that people have the ability to do more things or express themselves in more ways with fewer legal or social restrictions.
