Libertarian is often mistaken for “accepting everything”. That’s actually what I would call “libertine”. Libertarianism is a political philosophy, not a blueprint to run every detail of your life. It simply states that you don’t want people arrested for doing things that don’t harm anyone with their property, regardless of if you like it or if you hate it. You don’t even have to tolerate it personally.
Opposing something vehemently is part of how a healthy market operates, as is supporting something. You’re not stifling anything by simply casting judgment. You’re just being an actor in a market.
