Everyone is allowed there own experiences and relationship with their own bodies and lives. Fundamentally, if you are a Body Positive influencer, you should be more than fine with losing weight if you want to, no issues there. People who jump down your throat for losing weight as assholes and should be annoyed.
THAT BEING SAID
Including a line about being able to wipe yourself is a pretty dickish thing to say, given several reasons. Not only is your audience probably made up of a good chunk of fat people, but it's something that a lot of people who are fat struggle with, and often don't like to be reminded of or have mentioned publicly. I don't necessarily think it's "ableist" to say it, but it's definitely something you can get people being annoyed at.
>>42428While this reply does have some stuff that often marks hallmarks of SJW stereotypes, they're kinda not wrong here tbh. Mobility aids can actually be a necessary part of healthcare, and she clearly knows that "hey you're so fat you can't wipe your own ass" is something that is pretty humiliating to have brought up.
Like be as proud of your weight loss as possible. Seriously, it's good that people have that control and can do something legitimately tough. Just don't be an asshole and pull the drawbridge up from under you.
