Good or bad, it does mean a general increase is "unique" behaviors which are taken for reasons besides "its good".

Diversity is important, but it has the drawback that compatability suffers. Monoculture is no better, but the tendency to dismiss what others find unique is a recognition of the general (biological) strategy, to conserve some status quo to build community.

General advice, don't have strong feelings about what others like - if they enjoy similar things fine if not their opinions are not worth much in the first place. At the same time, don't be afraid to enjoy what you like or find your tastes change over time, it's natural and not necessarily wrong.

Worst thing you can do to a young person, be old, and tell them you love everything they like - either they will think you a foolish old person or be devastated they aren't as hip as they thought they were...
