I disagree with many libertarian positions as well. Support them on some - primarily those resulting in more freedom and less government.
“Our Constitution is made only for a moral and religious people. It is wholly inadequate to the government of any other.”The libertarian claim to want “less government” is at odds with their advocacy of social liberalism, which requires more government to rule over it; the cause, of course, is the abandonment of private morality.
