I am anti-capitalist but I am Libertarian to the core as far as social values. People can literally do anything that is consensual and not hurting anyone and not only is it fine but it's also none of my business.
And people don't have to like what you like, and they don't have to partake in what you partake in. People are not obligated to be into you romantically or sexually and it's none of your business what someone else is into unless you are dating them.
