Nonsense and dishonest.
True libertarians support abortion and always have.
You can claim that they misunderstand their own position, but you should quit pretending that it isn’t their position.
Abortion and gay marriage, and already they have given indications of supporting child porn.
That is absolute poppycock. The true libertarian position would eschew government sanction of any marriage, and leave it a religious ceremony.
Now, what Libertarians are doing, may be a different story. But any rudimentary understanding of basic libertarian philosophy would not allow abortion, child porn, or government license to marry.
