The only difference I have with the Libertarian Party platform is in the area of Abortion. One of government's legitimate powers is protection of its citizens lives, and a preborn person is still a person.
One of the most passionate advocates on this threads in defending Libertarianism is a hard core Christian , and coincidentally, a hard core atheist and libertarian posting on this thread is also a hard core "Right to Life" advocate (from what I've seen on this forum before).
Please select a narrower brush before you start painting.
You'll find that many libertarians actually agree with you on the abortion issue; most all the ones I know here on FR do, including myself.
I agree wholeheartedly, although I'm only a "little-l" libertarian. Matter of fact, I've only seen 1-2 libertarians on FR who disagreed.
If you consider the case of Islam - a religion of inolerance, coercion, conquest and cultural genocide - the distinction's pretty clear. And not even all Muslims embrace that particular worldview.
What is clear is that those who resort to violence in order to silence those with whom they do not agree, those who would murder others whom they believe would stand in the way of the achievement their perfect world share a common heritage and pedigree of ideas.
My own personal take on faith and matters of belief is that the farther one looks outside onself, the farther one is from the truth. It's one the very very few of Jesus the Master's messages that has survived intact over the centuries. It's a message that every great teacher/master has in common.
