LOL, not much to cling to is it?
1975 Candidate Reagan speaking to a libertarian magazine and trying to win them over just paragraphs before he proceeds to disagree with libertarianism and show himself as a social conservative and strong on national defense, yet here we are almost a half century later, and that quote is all you have.
Here is something more appropriate and relevant to this thread, the 2012 libertarian platform on homosexual marriage and the overall homosexual agenda what they are promoting with the GOP.
“”1.3 Personal Relationships
Sexual orientation, preference, gender, or gender identity should have no impact on the government’s treatment of individuals, such as in current marriage, child custody, adoption, immigration or military service laws. Government does not have the authority to define, license or restrict personal relationships. Consenting adults should be free to choose their own sexual practices and personal relationships.””
Personal relationships only? Why are the libertarians so prudish and authoritarian? What about persons and animals, if both sides are willing? Lots of people would like to officially marry their animals and force the rest of the world to recognize their love.
Um, I actually agree with that, for the most part: you see it's not government authority that defines the relationship that is marriage, it's God Himself, giving the government the power to "define, license or restrict" such is giving to it that which is not rightfully theirs. Moreover, suppose you gave those powers to a government perfectly agreeing perfectly with your own view-point... what would happen if the government came to disagree with you? They would simply use those powers given to them to "define, license and restrict" as they willed.
In short, not every power or authority is properly ascribed to the state.
PS "Consenting adults should be free to choose their own sexual practices and personal relationships" also means that they are free to suffer any consequences of that choice.
