But my whole point was that if it's an empirical statement, then we shouldn't be offended by it.

Yes, well... I don't agree with your point!

Some empirical statements, orthogonal to truth or falsity, are offensive. Virtually any claim can be made in an inappropriate way even if it's not intrinsically problematic (if someone shouted the multiplication tables at the top of their lungs in a public space for an hour, I might not use the word "offended" to describe my reaction, but I would sure want it to stop). Some claims can be made in a normal tone of voice during a conversation between consenting conversational partners and still be offensive. Many insults are empirical in nature. Slander/libel is generally empirical, although it's false if it can be described by those words. "I fucked your mom" is a claim about reality, true or false though it may be in any given instance; most people will be offended by it and they aren't wrong.

The particular statement under evaluation here is problematic for the reasons I outlined. Even if the statement is true and its content is appropriate - even if we assume that the man's daughter wants to grow up and marry a man and is perhaps actively soliciting advice about how to appeal to a wider pool of suitors - then he owed it to her to be gentler, less judgmental, and less endorsing of the stereotypical pattern about which he was trying to communicate information. Maybe "Well, a whole lot of men value domestic ability in a prospective wife - cooking, cleaning, that sort of thing." Same information, less harmful baggage.
