Since when? The only thing ive ever heard from them is im beautiful/healthy no matter my size and that is wrong. The healthy part is obvious and its just people being lazy or unable to afford healthy food [which yes its incredibly hard to eat healthy if you dont make a ton but its also down to portion control so either way its a choice unless you have legit medical issues ] and the attractive part comes down to personal preference.
The whole bad person thing ive never heard before.
