From the video as far as I remember the issue with Ardlings was that they made the approval numbers but the associated comments were generally "Meh!".No, of course not.
I am suggesting that there's a sizeable number of D&D fans who are anti-furry, that there is overlap between furry and queer culture (and similarly overlap between anti-furry and anti-queer arguments), and that some of the reaction to Ardlings is due to this factor. It's obviously not the whole picture, but without accusing any single person, I think when you look at the reaction to something like Ardlings vs. Goliaths, it's clear to me there's a more vehement dislike for the whole concept. You could call it something like the "anti-pink hair faction"-- there's always been some people in the D&D community who want to gatekeep it from people who are just a little too weird for their tastes.
