It’s the son of the artist, right? Did the son have anything to do with Batman? Did the son’s sexual orientation have anything to do with Batman?
What else is relevant about the son? Was he an artist? A writer? What did he do for a living? Did he have any relevant health disorders? Food preferences? Did he have any children?
BROADLY SPEAKING, your sexual preferences are the least interesting or relevant things in any conversation, unless we’re considering dating each other.
I don’t know the history of Batman so maybe it’s actually relevant, but my gut says it’s just not.
