i agree with MP.
“on the other hand many dolts find it unreasonable to not want to marry a fat lady.”
If by ironic you mean that people could believe simultaneously that a man should compliment his date/wife on her physical appearance, and then also believe that a man shouldn’t be so concerned with superficials, you are assigning generalizations superficially.
No one believes that a man should marry someone he’s not attracted to- obviously.
But if he appreciates how she looks he should (in the appropriate time for whichever circles you belong to…) tell her so. That’s separate from not wanting to marry someone you’re not attracted to.
