Even if we were to assume that there could be a set of standards in regards to what does and does not count as art, and which subjects are and are not worthy of exploration,* "glorifying" is an entirely subjective term that is worthless in this context.
No one person or group of people should be allowed to act as arbiters of what kind of art and media other people can and cannot create or interact with. Don't like it? Don't engage with it. But there's more to the creative field than Thomas Kinkade's whole thing of "art should always be uplifting and feelgood and should never challenge me and make me feel uncomfortable."
--Sincerely, someone whose mere existence is considered glorifying a degenerate and dangerous lifestyle by people like Collective Shout
* And we really, really fucking shouldn't because that's how you end up with lists of "degenerate art" and bookburnings.
