Or maybe it's not about intellectually lazy media-created categories like "hipsters", but more about sincere interest in an artist whose career spans 4+ decades -- far beyond when "hipster" was even a thing in the modern (not the Norman Mailer 50s) sense.
If by that you mean "responded with an argument to a vague and contentless accusation", then yes.
Is there a more childish response to an argument than "ha! it got to you"?
(Not to mention that age-wise I'm far off from the "hipster" demographic, and was watching Bill Murray way before hipster was even a term. Not everybody is 20-something on the internet).
This site has been turning to shit for a while.
