You are right, it is just democracy at work, but I'm not sure that that is different from a group trying preserve its identity.
The interesting thing is that most people assume that democracy is inclusive, because everybody has a voice, but in this case, the inclusive thing to do would have been to watch something that only one person wanted to watch, to make them as a minority, comfortable, whereas the democratic thing to do is to ignore the opinion of the minority as not relevant to the views of the group.
Where the discussion becomes difficult, I guess, is when the dividing line between majority and minority coincides with that of privileged (PS. I hate what this word has come to mean) and unprivileged.
