It's inviting judgment. Any position on it, positive or negative, joke/serious, etc., is a judgment.
Asking/insisting that people not judge is an act and a position-taking of it's own, not a neutral position.
I'd say that this thread touches on very complex issues about male-female relationships - that old Marxist-feminist analysis of the financial-sexual transaction of marriage. That's why it goes deep.
I'd say it raises questions about the location of jokes. eg. This joke may play quite well if one has achieved a utopic space within your particular male-female relationship but plays not so well in a different location, where the target audience may have an eye on a distinct lack of such a gender-equality utopia.
It also touches on how to interpret information posted on a public forum. In a sense, because it's now on a public forum, the fact that all this is played out by two loving, consenting adults doesn't really matter. It's now a public act and its interpretation can't simply be limited to how those two adults interpret it.
Posting in AIBU is an act of inviting interpretation and an act of taking an individual act out of a private context.
And, yes, i know that is all quite heavy for a Saturday night thread but ... what the hell ... it's posted on a public forum, it's now general property and I can make of it what I will.
To be honest, I don't really care much about the initial question; I'd guess it was designed as a bit of a wind-up, for those of us steeped in Marxist-feminism and its offshoots.
But I do get a bit cross about posters telling other posters to be quiet. The bit of me that isn't fond of censorship gets a bit miffed.
