Here we have this eatbeast, who may just have severe PCOS, but given her croaky voice may also be on gender-affirming supplemental T.
She is not only some form of trans, but is so dedicated to broadcasting her identity as a non-cis, non-hetero, non-woman, she's wearing rainbow glasses.
She is very obese, and still gaining weight, so she's shovelling in at least 3500 calories every day, and possibly more. She knows she's gaining weight because there are fewer and fewer chairs she can fit into, so this weight gain is intentional—she is aware of it, yet does nothing to stop or reverse it, despite the problems it creates in day-to-day living.
So basically, we have a mentally-ill attention-seeker, who is disfiguring (and will ultimately destroy) herself in the name of the oppressed, "outsider" identities she has adopted—and she's demanding that the rest of the world change to accommodate the self-inflicted manifestations of her mental illness.
Yeah, good luck with that, crazy lady. I'd rather accommodate the schizo guy in my neighborhood who believes cats are highly-intelligent extraterrestrials who are here to observe humans in action and telepathically relay all our sins to the higher beings who are watching us, and will one day judge us. At least he's nice to cats he meets, and spends his tugboat to feed a feral colony.
1) There are two kinds of vegan diet: the kind of vegan diet that includes the overpriced fake products that are highly processed, artificial, full of sugar, salt and fat and still taste like shit and the raw vegan diet where you only eat veggies and fruits and weird superfood concoctions and protein powder.
Uh, no. I'm not a vegan, and would never voluntarily go back to it, but I know many longtime vegans who have managed to do well and maintain good body comp by avoiding either of those two extremes. If you can cook, have a solid grasp on nutrition, and know what's garbage is to be avoided, you'll do okay.
Most noisy vegans in the SJW crowd, however, are incompetent at taking care of themselves in an abundance of ways, including feeding themselves properly. They cannot "adult," as they like to put it. Plus, a case can be made that nutritional deficiencies and gut dysbiosis from being at either end of the shitfood-orthorexia spectrum contributes to the kind of mental health issues we see on display in that crowd.
If veganism as seen on social media looks like a split between two extreme and disordered types of eating, it's because its loudest proponents, who make veganism a big part of their identity, are extreme and disordered people.
2) The only processed vegan food that does not taste like death and is not ridiculously over priced is the candy so some vegans eat a lot of it.
There is tons of regular processed shitfood that just happens to be vegan, including Oreos and potato chips. Then there's cheap, easy-to cook simple carbs, such as pasta and white rice, upon which one can dump seed-oil-based fake cheeses, soy-based fake sausage and meat, etc.
Fat vegans eat overwhelmingly from the white-beige-brown end of the spectrum. They're really just carbotarians, adding low-quality fats and lots of either salt or sugar to give them some semblance of flavor. They're the kind of people who think corn and potatoes are vegetables, rather than just more elaborate forms of starch.
3) Most vegans can not cook.
This is the one point I can wholeheartedly agree with you on, if only because most people—especially young ones—can't cook. They can assemble; they can re-heat; they can boil pasta or use a specialized appliance that cooks rice for them, but they cannot cook.
4) All of them are crazy.
The noisy ones on social media, or the ones you know IRL who have to pre-emptively announce they're vegan by various means (I saw a fit, 30-something guy on a bike the other day, with a messenger bag with the word VEGAN emblazoned across it, and thought, "FFS lad, you must be a smug bastard")? Yeah, they're all fucking crazy. But then again, so is a society that makes it possible to form your personal identity around what you choose to eat from the countless and abundant options available.
