I'm not 100% sure what the argument has become. Their source even lists the reason "scissoring" as it's commonly shown in porn (the barbie thing) isn't the real act. I think the issue is that I am using the term "scissoring" to refer to the barbie thing, as that is how the term is used among every lesbian I have interacted with as well as in all the writing about this topic from lesbians that I have engaged with, and their source is using the term "scissoring" as an umbrella term for "tribbing" (which they have clarified they're doing).

I don't think that we disagree on concept, just that they are arguing from a position of slight semantic difference. "Scissoring" the position seen in porn isn't "real" tribbing. It's a bit like the sex tips in cosmo - are there men that might enjoy having a doughnut eaten off their shaft, or who enjoy being jabbed in the balls with a fork while getting head? Yeah, probably, but I'm pretty sure we can agree that those specific examples shouldn't be used as the common representation of what a "blowjob" consists of. Nor do I suspect anyone is going to argue that the insane and grotesque sex acts on urban dictionary are "real", even if someone might have tried one of them once.

Anyone can do anything, and people are weird about sex - but as they're intimated, the common depiction of the sex act in porn is a bad representation, and that is all I have been saying. If the argument truly is just that they think scissoring refers to all tribbing, their own sources show that's a contested claim.
