Abolitionists were once thought of as being on the lunatic fringe. Now we accept their position as philosophically correct. As for libertarians, I entirely agree with those that point out national sovereignty as being inconsistent with humanist values.
However, just because you are philosophically correct, that doesn't mean you aren't part of a lunatic fringe. The differentiating factor is how you interact and propose to interact with society at large.
