Curated Tumblr

Ah, yes, because the disagreeing with you means "infatuated by the random picture machine", right? No room for someone to think that it's, I don't know, another tool a person can use in the creation of art? Kinda like how not every cellphone picture is high art, but you wouldn't say you can't use a camera to make art.

But no, clearly you're the arbiter of knowing how stuff works and, what art is, and how others appreciate it.

object permanence is beyond infants but by your logic that would also be pretense

Yes, because developmental psychology is exactly the same as "art critique".
It's pretentious because you're responding to someone who disagrees with you by asserting that either they don't understand the subject technically, or their entirely subjective experience of art is somehow lesser than yours.
