Well, the libertarian platform is pretty clear that they want homosexuals in the military, adopting kids, marrying and so on. And illegals are fine, too.
So if you disagree with any of the above, you should take it up with the official libertarian people.
Why? The original poster of the thread wanted information on what libertarians believe as a political philosophy. I have tried to explain that, but as I noted before, I don't necessarily agree with them.
Your request is no more logical than someone suggesting that since you no doubt disagree with the Democratic party platform, you should "take it up with the official liberal people". So what are you waiting for?
