Personally i have always said that the world owes you nothing and neither do other people, i know that sounds harsh, but if you actually think about it, there are what like 7 billion people on earth, you cant control what all of them post and dont post.
I agree on putting a disclaimer on violent/graphic content, but as far as eating disorders go, thats on me and no one else. you will never be able to go out in this world and not see something that will trigger your ED. you could go to the shop and see a supper skinny girl and it would trigger you, she cant wear a trigger warning, so the thousand things that dont have trigger warnings overrule the few videos that do.
I also understand people being in recovery and actually actively trying to avoid triggering themselves but at the end of the day you do yourself more harm by trying to be over protective and sensitive because you cant shield yourself from everything . You see skinny people, dietary/low cal foods everywhere you go, how are you going to skip seeing that.
Also some people with EDs are creating a toxic space on the internet due to insisting on trigger warnings on EVERYTHING because people literally cant post a picture of themselves in a bikini without someone going on about how they are trying to recover from a ED and the content is triggering to them. EDs have too much of a broad spectrum to use trigger warnings on because not everything that includes clothes, food, diets, exercise,skinny, over weight people, gaining weight, losing weight, have to do with eating disorders but eating disorders have everything to do with those topics. so we will always find something to relate to or trigger ourselves with, and thats on us, not these other people just living their lives.
