Very poor taste, especially with Engerland and Russian footie hooligans displaying who they'd like to poke in the eye, the Orlando shootings, murder of the two police officers in their home (in front of their child) and now the murder of the Labour MP. Don't want to sound sanctimonious but honestly, casual talk of violence isn't on.
I agree, this is in poor taste - what on earth is funny about threatening other people with (even pretend) injury? We should be discouraging violence, real or virtual in all its forms.
