Sign seen in a college town: Do you find it funny?

I saw a humorous article about twins that I forwarded to my own set of twins.

My S sent it back with the note that a trigger warning should have been included, because the author of the piece had (jokingly) said that fraternal twins dont count as they aren’t real twins (and obviously my boy/girl twins are fraternal) - and how dare his twin status be marginalized and oppressed and considered inferior to identical twins. (Of course this is all tongue in cheek.)

But really, one can get all ridiculous over oppression and marginalization and trigger warnings. It was a common joke being used to entice people to indulge in caloric goodies. No more, no less.
