So back to your question;
Libertarians don't get any privilege in view outside of the idea of consent between two willing parties.
If you force me to engage in the act, you're encroaching on my ability to consent or volunteer.
This is the base layer of society we're talking about - not specific opinions.
Of which I can practice and discuss with you no problem!
But they're my 1nak not something I'm willing to shove down your throat & label you a heretic for not complying.
