Yes, the plural will create ambiguity without the Oxford comma, the singular with. Since both create ambiguities, you should go the route that requires less needless punctuation and simply rephrase when the occasion of ambiguity comes up. There is never a correct time to use the Oxford comma.

For what purpose did someone make an edit where Stalin isn't a stripper in the last part?

Are you aware of the irony of this post?
Nolan Miller
That's an inverse of the situation. Using the Oxford comma in the singular creates ambiguity as shown in the OP's post. However, the plural, as seen in your pic, creates ambiguity without the Oxford comma.
Your pic is the original and the OP's is a perfect refutation of it.

That's not what irony is. Irony would be if in making that post I intended to convey that OP is not autistic. I'm fully aware of what I am, and I think it's important that he is likewise.

Well, alright then. Makes sense.

Autism is noticing that strippers are hired, not invited.
