Absolutely. I have been overweight since i was about 7, been a size 16+ since age 15 and currently am an 18-20. (according to primark sizing)
I've been abused my entire life, from school bullies to having multiple instances of strangers (usually group of teens) shout fat abuse at me across the street, never seen them before, minding my own business, completely unprovoked. Also find in the case of any disagreement with someone, e.g getting pushed past in a shop, no matter how civil and polite i am, most who feel the need to say something to me, always jump straight to a fat insult.
For instance yesterday, 2 teen girls ran across the dual carriage way in front of us making us have to brake sharply to not hit them, their response was to yell "fat cunt" at me, and i wasn't even the driver!
Being fat isn't socially acceptable, it gets a lot of negative judgement. It's like if you're not slim enough for someone to find you attractive they take offense to your size like its a slight to them, assume you're lazy/greedy and look down on you like you're a lesser being. I've never recieved a single compliment or positive attention from someone i dont know in person, or who doesn't get to know me online annonymously first before seeing a picture of me.
I wish i was invisible, i hate being looked at by people because i'm so embarrassed and ashamed of how i look and the way i get automatically disliked for it.
