To be honest, I have seen those jokes before. I think he copied and pasted those jokes from other Twitter accounts in a bid to gain more popularity. I could be wrong, but I think the jokes were daft, rather than offensive. I felt offended at them because of who he was, rather than the jokes themselves.
Anyway though, here's my comment on Page 7 in the Metro:
The Daily Beast ran a full online article about it, which can be seen here.
I'm actually glad that it wasn't featured by too many news agencies, as I think that would do a lot of harm to both Amnesty International and the stigma around schizophrenia. After all, when an unflattering picture of Beyonce made its way onto the internet, she asked for it to be removed. What happened? The picture went viral. Likewise, I think if too many news agencies report on this, more people will make schizophrenia jokes and will add to the myths and the already huge stigma.
Ciarnan Helferty made a bad decision numerous times tweeting those jokes. But the big picture is, if he is dragged any further through the mud, Amnesty International will follow him. Let's all shake hands and move on!
