7777777, thank you for providing citations for your sources... guess a bit late; better than never. You also edited those in pretty late. Though in this case, it helps the record, ever so slightly...
The only problem with it, aside from it being questionably on topic, as the topic is a bit of humor in any case, is that it was selective cherry picking.

"When photons interact with electrons, they are interacting with the charge around a "bare" mass, and thus the interaction is electromagnetic, hence light. This light slows the photon down." - BuleriaChk
7777777's idea about the largest natural number seems quite appropriate for the golden ratio award, in that it can be refuted immediately by adding one. Nonetheless, I'm still working on a formal write-up for one of John Gabriel's howlers in circular reasoning.
I make a nomination: all those users here who accept dy/dx but, at the same time, deny that dx is an infinitesimal
However if you feel otherwise, please provide an epsilon-delta definition of derivative that either mention it being infinitesimal by a renounced mathematician, or a book used in multiple real analysis courses, you'll need to cite at least 2 courses from proper universities that state they use it, and then the book itself, page and definition number.
If you can do that I will accept your nomination if you can state a single person to it.
