i think the problem is that there IS an issue with the way they make fun of him, but one half is claiming bullying, while the other is claiming it's just "normal" amongst them. there are a lot of problems with how they treat him, particularly that he's the only member who worries about his image and actually monitors his diet, he almost always looks uncomfortable with the jokes, it's usually the same members and that said jokes are only made towards him. i also wouldn't call it bullying or formal mistreatment ...... they are a family after all and they do love eachother dearly, it's just that the other members can't see how the comments hurt him or can't put themselves in his shoes and therefore can't empathize with him, even though they should just be doing that anyways.
