A sexist remark or am I overreacting?

[temporarychangedusername]

I was attending a couple of days ago quite a specialised course (STEM area) and a topic of the importance of communication came up. It is indeed an area where many people lack "softer" skills - i.e. they can do the technical bits, but can't then explain the significance of results to a non-specialist.

The lecturer said "I always say to my students - you need to be able to explain it in such simple terms so that your mum could understand".
It rubbed me the wrong way a little bit. Why not "that your dad could understand"? The audience (as much as I could tell from the online meeting) was indeed young (early 20s) and overwhelmingly male, but there were a few of old hags (and mums) like myself attending as well, and a couple of younger women too.
I am not the one to be mortally offended by any slip of the tongue, but would I be unreasonable to ping a private message to the lecturer to suggest that may be there could be a better analogy he could use next time? Or would it be totally OTT?

Young people fail to understand old type humour. and fill their heads with words like sexist and ageist, etc,and give themselves headaches,by complaining about everything these days.

The reason being that we have had less in place for several decades now discouraging this and also because students can and will now complain about every so gke word they take wrongly.

Which is why I'm surprised this lecturer said something like this. Its so informal, it makes him sound a bit uneducated. He is lucky the opis only going to contact him orucateky, because most students are able to make anonymous complaints and them the lecturer has to watr a few hours having the complaint detailed to them by their manager, responding to it and possibly having it exacerbated if it's serious enough.

But all lecturers know this - so why make such a stupid, sexist remark in the first place? It would be offensive in any professional workplace setting, possibly not in a builders' yard or on a worksite but in thus context, it's weird.
