Gather 'round, children, as I share with you the tale of the most uncreative creative writer Grammy Slowboat ever encountered ...
I can't strictly call her a Tumblrista, because I knew her before I was ever aware of Tumblr. She was definitely in the SJW mold, though. She was a pot-smoking, occasionally transgender lesbian Native American artist, and every single thing she wrote was about a pot-smoking lesbian Native American artist character who was usually being oppressed by The White Man. OK, including things from your native culture or personal experience in your works is cool, right? Everyone does it, and it helps add dimension to your writing. The problem was that she had no other ideas.
Worse, she had no other topics of conversation. She would monopolize discussions with her themes, her work, her inspiration, and how all of them derived from her incredible experience surviving the gulag of modern-day America which can't tolerate a pot-smoking lesbian Native American. Everything was about her oppression.
Her work was ... not commercial, shall we say. She was writing a novel themed around the medicine wheel, but it was borderline-incoherent and, as far as I could tell, consisted mainly of the main character struggling against a world which hated her for being a pot-smoking lesbian Native American. She would take up massive amounts of time at our scheduled readings, and nobody ever dared to say "You've used up twice your allotted time, and now the others following you won't be able to read" because that would have been an attack on someone bravely bringing forth her narrative of the intolerance faced by pot-smoking lesbian Native Americans.
I have no idea what happened to her in the end. She probably graduated and won a shitton of literary awards.
As a writer, that fucking kills me inside. I don't mind recurring themes in stuff. Hell, a good chunk of my stuff that I'm working on is how extremism is fucked up regardless of its outside dressing. But holy fuck, that's simply lacking in any creativity meets a victim complex the size of Jupiter.
Modern America, even for the working class, is not anywhere close to being a damn gulag. The working class has several safety nets if one is under a certain income bracket, so you don't starve or die of disease. Anyone who acts as if it's entirely dog-eat-dog in modern America has never lived paycheck to paycheck, had immediate family live paycheck to paycheck, lived among the working class, been the working class, etc. It's painfully clear they're not aware of such programs aside from a very abstract "the politicians are talking about food stamps and Medicare today," including the girl you speak of.
As for IRL SJW experiences, there's this one girl I got into a debate with because she was talking about what's dubbed "imposter syndrome." I point out that it's akin to the Dunning-Kruger effect and that, in more recent times, imposter syndrome has been more thoroughly researched and is not limited to women. To define terms, imposter syndrome is a term coined in the 1970s of this idea that competent women saw themselves as imposters at their jobs. In more recent times, it's clear that it's unisex. The Dunning-Kruger effect relates to the grossly incompetent are ignorant of their incompetence, while the competent underestimate their competence.
Meanwhile, I asked her to give forms of evidence for her anecdotes that weren't anecdotal evidence, as I'm very much a stickler for evidence. She was also supposedly talking about someone else's paper and didn't do the research herself, nor did it sound like she read it in its entirety. She insisted that her "lived experience" was somehow valid for making sweeping generalizations of concepts.
On top of that, she had the most smug expression on her face and this condescending as all hell tone. The smugness made it clear that she thought she was so much more high-minded and open-minded than myself because I don't believe in things that I'm not given evidence for, especially not things that set off my bullshit detector. That's not high-minded or open-minded. That's just damn gullible, being so open-minded that one's brain falls out.
This was also the chick that walked at the end of the college line instead of where she was supposed to because she insisted there was a stalker who'd go after her and that they'd see her on the local TV graduation broadcast. Considering she completely drank the SJW/third-wave feminist kool aid, she just has a victim complex.
