Does it really make me an asshole to not want to participate in someone else’s delusion?

Clinical depression and homosexuality were "someone else's delusion" as recently as the 1800s and 1990s, respectively.

No one is asking you to participate so much as to avoid making pointless, dismissive comments.

Yes. That is basically the definition of "inconsiderate."

Furthermore, it's rude to suggest that your social constructs are the only non-delusional ones around.
