As I said in some other thread...
Hipsterdom is a state of the heart and mind, and can manifest in any form.
Thus, looking at someone with a beard and saying "he must be a hipster" is not (logically) correct.
In addition, Mr. Reeves exhibits the style of dress and personal accessorizing that was popular in the death metal community (1) during the deathcore years and (2) for fans of Unique Leader bands on the West Coast.
If you want a simple answer, hipsterdom is inauthenticity + manipulative opportunism.
That requires a deeper look than skin-deep...
