Do Libertarians support open borders?

Do Libertarians support legalizing methamphetamine, in my neighborhood?

Do Libertarians support legalizing gay marriage, polygamy?

Do Libertarians support defending ourselves, pre-emptively perhaps, against 1.2 billion muslims?

Some do and some don't, just like Republicans and Democrats. More Libertarians belong to the Republican Party than Harry Brownes Libertarian Party.
Many are leaving the Republican Party now that the RP is swinging left and they are changing the Libertarian movement. You can call them Southpark Republicans or Neo Libertarians, but the result is the same. They will be the dominating political power of the future.

Do Libertarians support legalizing gay marriage, polygamy?

Libertarians would probably say the government has no business in marriage anyway. You don't need a license (government approval) to have children, why do you need one to get married?
