If global means everyone, and I think that's what it means here, then someone has to comply to someone else's worldview. To have a true global community the people who don't want a global community have to be part of it just like everyone else. If people can opt out of the global community and build their own insular communities which they determine the fate of then it's not a global community, it's just a community. A global community that you can opt out of is a solecism.

Taking Facebook as an example for a global community: Just because I have the opportunity to participate in each and every Facebook group I don't have to do so.

Yes, in real life there are compromises to take. You have to accept that in order to thrive in the world you have to comply to some of its rules. I'm very much a cultural imperialist in that I think that an open-minded, tolerant mindset is superior to isolationist, absolutist ideas.
