I honestly don't think she realizes how big she is. I think she is in denial. The way she thinks everyone is after her. Everyone really wants a 500 pound girlfriend to take care of. She's more of a hassle than an equal in a relationship.
I also saw on her twitter that she is excited for pride month. I'm not sure if she's really a lesbian. I know this topic had been talked about. I think that she likes women because they are easier and will accept her shit more than men. I'm a lesbian myself, I think she relies on people's natural instinct to take care of the ones they love. I'm not sure if anyone has ever loved her.
I'm unsure where the idea that women are easier marks for social parasites like AL comes from. If you're a disordered person like AL, everyone's a mark. If she was jadedly altering her sexual preferences in order to have access to people who are willing to take care of a massively obese woman who won't work and is a spendthrift, she'd be bisexual because there are definitely as many caretaker men out there as there are caretaker women and it would double her pool of prey.
Men take plenty of shit in relationships. Think of how many weak-willed and lonely men there are out there. Think of all the captain save-a-ho types, all the dudes who tolerate extremely unpleasant women because they watched their dads do it. There are memes about those men that are akin to the U-Haul lesbian memes. AL is huge, but there are men who like huge women. AL would have far more economic security if she went on a fat dating site and nailed down a dude who would want nothing more from her than that she eat and lounge around. Such men are generally not captains of industry but chances are they will make more money than someone like Becky and are going into the relationship knowing that AL will primarily be a consumer in the relationship.
If anyone here recalls Quirky Rosie, she was a body positivity girl around AL's age who is massive and ugly to boot. People discuss whether or not AL is pretty but compared to Rosie AL is a beauty queen with the taste and carriage of a queen. Rosie is unattractive, has visible fungal skin growths from not showering, weighs over 500 pounds, and has the charm of a dirty litter box but she went online and landed herself a whale lover and moved across country to be with him. AL could do that well very easily because although it seems like these huge women are everywhere, women AL's size are still relatively rare and most of them are not that fat so young. They bulk up after years of marriage and childbearing. Men who want a super-obese young woman have far fewer options than you might think and will tolerate lots of nonsense to obtain one (those who are keen observers of the fatosphere can likely think of other online famous fatties who are foul human beings who landed a man - Amber Sarah also comes to mind - over 600 pounds, crazy, useless, personality disordered and ugly and she never is without a man for long). A young, childless woman AL's size could also find some lump of a country boy who loves her for who she is inside and would let her sit around the house in some sort of misguided chivalry.
Men are as willing to tolerate and enable AL's shit as much as any woman.
