Maybe not to feed the fearful part of the brain but to be recognized by people with similar values and ideas. It's like if you were a scientist in a highly religious family that thinks science is the work of the devil. Or a very religious person in a very scientific family where everyone thinks religious people are idiots... finding a community can be helpful as long as the people involved are good people. Feeling heard, understood, and recognized is a really important part of the human existance.
