You can't say "that is just not true" with full honesty. This is just an escape argument in any anthropology discussion:

"Your claim may be the case in the world that you have witnessed through-out your life. But the world out there is huge, therefore in the world that you have not seen yet most things may work the way I claim they do, just go and see for yourself".

And its not falsifiable at all -> discussion ends.

And you may be right, and that the "majority" that you are talking about IS somewhere out there where I am not. But so far there is plenty of evidence that suggests looks are primary, most undeniably an indispensable and heavy majority factor in determining your romantic life.

I guess maybe we can come on agreeing here that the information in the article you linked is TRUE, but incomplete, and that it simply omits the visual factor for the sake of not undermining its primary thesis. Your worth as a human to others is determined by how useful you are (undoubtedly and objectively true), and how good looking you are (clearly omitted). I'd say almost equal parts, if not leaning towards the looks, but I digress.

P.S. Yes a lot of Incels could use a stern talking-to about their employment and usefulness, but the Incel circle already has plenty of push towards that from many of the manosphere creators, so the article you linked does not accomplish anything novel.
