Regarding the apparent popularity of Josh and Wes - I think it's depressing. You can be a horrible person and do unkind things but you'll get away with it as long as you're funny and entertaining, people are so shallow.
The Dr Alex/Charlotte Crosby thing on IG is crazy. She posted a horrible comment about his appearance and his account responded to say that they were disappointed that someone with such a high profile, someone who has spoken out about online bullying and how hurtful it is to receive personal appearance comments, would choose to do that.
She's now received thousands of comments from people basically agreeing that it's wrong to shame someone for a physical attribute that they have no control over, and she's now added a video to her story in which she's crying and asking people to stop saying horrible things about her, apparently unaware that she started the whole thing by..um..saying a horrible thing.
