I disagree. Voluntary communities are made up of volunteers. There is nothing coercive about it. Voluntary communities provide a way for like-minded people to live in harmony. If your beliefs do not match the beliefs of a voluntary community, you are free to to argue that your beliefs should be included, leave the community, or start a new one and include anyone who believes the same things you do.

Granted within current systems you can do the first, but you are completely unable to do either the second or third.

I live in the USA. But I did not volunteer to live in the USA. I certainly may be able to move to a different country, but I certainly won't be able to find a country with the same beliefs as I have. (The States with our Constitution and Bill of Rights is likely the closest to my beliefs).
