I think maybe this is a cultural difference (or my house is weird I really doubt anyone in the nuclear family is Neurotypical so this may be the Autism House Coping Skill ™️ Thing ) since evidently lots of people on the subreddit are baffled by this.

Okay admittedly I would never make the "Get Tomatoes when Robin says "get fruit"" mistake because in my house if you say you want to have fruit in our groceries it's UNDERSTOOD it's like "Fresh Fruit to Snack on" (Yes I know you can snack on like cherry Tomatoes. I don't. I'm allergic). But I really do think Robin is being unreasonable in this scene because... my problem with this scene is more "has this really never come up in the whole time you've been married"?

And Yes I think the "You wouldn't use tomatoes in a fruit salad" argument is silly because other than the fact it's pretty rare for us to make fruit salad, we would specify if we were cooking fruit salad or w/e.

I really think it's both Racism and being horny for Robin that sort of cause people to refuse to take Demetrius' side here.

I mean find the scene implausible (like I do) or that it doesn't speak to you. that's fine.

Honestly my headcanon for coping with this scene is that Demetrius is trying REALLY hard to mask and Resemble an Allistic person that that's more why Robin is saying "When Normal People Say..." Which ain't great but this is the game that until very recently didn't understand Wheelchair Etiquete in Penny's 2 (?) heart scene.
