There is whole world of people who don't care about Kardashians or similar pop persons, we are just not so loud about it and don't need to. Ie I don't have an Instagram, never will, even though I produce thousands of pretty cool pictures from travels and adventures that my inner circle often considers beyond their imagination.

People having this 'sheepish' mentality and having little of their opinion (or will to form their own opinion through fact-checking), instead taking opinions of others is nothing new - look at folks following fashion. People literally telling you how to dress, what is cool, what you should think and feel - yes its really that dumb, there is no nice way around that. Its also a bit of membership signaling - you are part of desired group, 'better' than rest. I guess you see what I mean.

In ignorance of this crowd mentality lies one's strength of one's mature personality. It could have played a great deal during evolution of human species as social one, but these days, it mostly leads to rather boring, unsatisfied lives.
