Good lord, I fell off that section of the internet long before the ponyism and genocide runs, looks like. I remember JDR from the OtakuWorld days (Furcadia, the original furry chat room/mmo originated from there btw) and actually slogged through all of Unicorn Jelly and PDH. She's what got me into pixel art back in the late 90s.
My two cents (source, experience with her type/generation) on her:
I can legitimately respect her as trans, unlike most of the younger generations. She's one of those who accepted that 'frumpy 80s cat lady' is as good as she's going to get in the looks department, and instead of trying to morph into a Bratz doll, she owns herself. It works.
She comes from an odd period of social change, given that 1959 birthdate. Consider her childhood especially with the fundie household, and the permanent fuck-you-dad attitude fits. This was also well before being a nerd became mainstream, as well as that brief period when nerds were sort of counterculture. On top of all that she's between the Boomer and X generations, if only barely. It's a time period before kids didn't need imaginations anymore - if you wanted to see yourself in something, you sat down and put yourself there rather than brigading the content creator to do the work for you. A lot of nerds of her era have the same wacky tendencies, and the creative types have that deep world building and imagination capacity. Jennifer just never really let hers go in favor of more settled-adult pursuits. She navel-gazed with the kind of intensity that only comes from that generational/social period combo and whatever weirdness she has going on mentally.
In that context the weebiness, scifi boner, furry tendencies and seedy hippie polycule business make sense.
I can respect the huge body of detailed work she has behind her, and the fact that a lot of it is still around to see is a little mind blowing. She's still a nutter, moreso now than before I think, but without the power of NASA or anything like that behind her, pretty harmless.
