Rights, religion, marriage: all living fairy tales that people make up, that are also not necessarily bad, but could come with a warning label that reads: "made-up." I pretty much agree with Christo-F, and it looks like he said the exact same thing.*
I used to think that there was difference between rights and privileges, but not so much anymore. Rights and privileges are the same, handed out by those in power of a certain group. The right to food, to water, to happiness and whatnot probably comes from our humane needs, which are not hurtful rights at all, but are still made-up.
Also, what I see as the paramount argument against using animals for food and things are not because they have "rights" or because life is "sacred." It's because pain, which is not a fairy tale, is not a pleasant experience and unpleasant experiences could be avoided.
The animal rights argument is what completely abolished the natural rights argument for me.
The greatest thing about fairy tales are that they can change. If gays want to join the pile of bullshit, why not.
