There's a bit of a trend to try and describe some communities as living in a bubble.The idea has become so deformed that people use the term incorrectly. So if people are interacting on twitter sharing similar views, they call it a bubble, if people have facebook timelines which show only their supporting views they call it a bubble, when revolutionaries are talking about torture and police brutality while most citizens don't, they call it a bubble.
I don't think people really understand what a bubble is as opposed to a community. A bubble is mostly defined by an unawareness of those around you, not by your preferences. You can't be in a musical rock bubble if you're aware that others like hip hop or house. The fact that you have a different taste or preference doesn't place you in a bubble. When you have preferences that are not mainstream, it doesn't put you in a bubble.
Bubble here is being oblivious to the reality of the world around you rather than relates to the choices you make. One particular example that stands out is the revolutionary bubble, which is complete nonsense. Revolutionaries are perhaps some of the most aware people of the existing contradictions in the country and the different communities and 'bubbles' out there. The fact that they've chosen a set of tastes and principles doesn't put them inside a bubble, particularly that their main concerns are the bitter realities of regime brutality that others want to shield themselves from.
The fact that other communities are not so accessible to them so that they can influence them doesn't put them inside a bubble, they just don't have means.
Also worrying is how many, even from within these circles, completely discard revolutionaries or activists as citizens. There is a form of elitism shrouded in the appearance of humility there. These activists are citizens too and just because they are trying to change things beyond their local scope doesn't invalidate their citizenship or opinions and most certainly doesn't warrant describing the whole lot of them as living in a bubble. In some sense, revolutionaries are the biggest non government sponsored coalition whose cohesion is based on a set of principles rather than an an institution.
People have used the term bubble to express their escape from the madness, in that sense it's building your own defenses against the surrounding madness, but there's a difference between choosing to isolate yourself and being oblivious to what is around you.
