This is why we can't get sh**t done. People really think it's uber cool to make fun of other people for their politics.
Personally, I don't think libertarians have any impact on whether things get done.
Regardless, why is it necessary to demean other human beings for their political beliefs?
Whilst perhaps not necessary, people are going to do it anyway, free speech is famed for producing views that others don't like. Besides, it's not like libertarianism is the only ideology to receive flak from left, right and centre (both figuratively and literally).
