Not all libertarians are pro-choice. Abortion is manslaughter at best and Roe v. Wade is a horrific interpretation of the Constitution. How anyone can say the equal protection clause of the 14th Amendment applies to abortion with a straight face is beyond me. My problems with gay marriage are that it’s being forced down our throats and the term itself is an oxymoron. I admit that I tend to be pretty libertarian when it comes to most drugs.
Yet the Libertarian Party is and has it in their platform as is their support for homosexual marriage.
National Platform of the Libertarian Party
1.3 Personal Relationships
Sexual orientation, preference, gender, or gender identity should have no impact on the rights of individuals by government, such as in current marriage, child custody, adoption, immigration or military service laws. Consenting adults should be free to choose their own sexual practices and personal relationships. Government does not have the authority to define, license or restrict personal relationships.
1.4 Abortion
Recognizing that abortion is a sensitive issue and that people can hold good-faith views on all sides, we believe that government should be kept out of the matter, leaving the question to each person for their conscientious consideration.
