I have been sitting on my hands for days over the whole "a BJD isn't a BJD unless it's made of resin and strung with elastic" debate I ignited on Tumblr by daring to disagree with that sentiment. As of now, at least half the posts are debating either the veracity of the elastic strung BJD exclusion or my right to disagree.
Fun fact: I traced this assertion that a BJD has to be strung with elastic back to a DoA post from 2018. It wasn't even an official post, it was just someone giving their own view. Somehow it has become gospel.
At this point it wouldn't even matter to explain to anyone that the reason polyurethane BJDs are strung is because hinged ball joints cast in that material won't stay in place. That's why polyurethane dolls have to have magnets and elastic. Pegs would just slide right out. Otherwise Super Dollfies would have been hinged just like the original Dollfies which inspired them, and the elitists would have had to find something else to justify their exclusivity.
One of my very last posts was a picture literally illustrating how little difference there is between an ABS BJD and a strung resin BJD. I posted this to my own Tumblr intending it to be my final word on the subject.
I think that's pretty much all I can say about it. I have difficulty leaving willful ignorance alone but I guess I'm going to have to learn.
