I don't know any more...

This focuses on only a small subset of liberty, of course.  We could also ask stuff like “Don’t like being told where you can work, or what jobs you can do?”  or “Don’t like having your money taken to pay for stuff you don’t support?” or “Don’t like having your house taken away so a private developer can build a shopping mall?”.  The rights being implicated here are to privacy, property, freedom of contract, and general personal autonomy.  They are incredibly important, and much broader than just the gay marriage debate (which is itself simply a minor example of government interference with liberty of contract) or abortion.

However!  The image is right as far as it goes, even if limited in scope.  I just wish more people would apply the principles behind it further.
