Dick Hebdige’s book (a standard sociology text) Subculture: The Meaning Of Style puts it down to something like that: the essence of a subculture is an awareness of style and differences in style.

Perhaps it also explains language diversity?
That is surely more down to drift—and xenophobia.

What do you mean? When in history are you referring to?
The period during which language evolution happened.
Xenophobia acted to help prevent cultures from combining, probably resulting in increased cultural diversity.
