Well, yeah. Here’s how a libertarian view can be summised…

Gay marriage is illegal. I think the concept of marriage is pointless and disagree with it. Opportunity to vote for gay marriage comes along, obviously vote yes, nothing to think about there. Nothing about it takes liberties off anyone, it just gives them to people, regardless of whether I align or even agree with them or not, it’s about them and not me. Making it about me and taking actions against liberties is obviously anti-liberal. That can only be achieved with poor empathy skills.

So then how would a conservative handle that same scenario, hm? Well for starters they’d hate me and the gays for “desecrating” their weird little religious legal love contract ceremonies that are entirely detached from love…
