I could be missing something, but from what I can see, the screenshots of these pathetic chats by these boys were referring to some other chat where other boys were apparently talking about shagging the “poorest” girls? Nobody has provided a direct screenshot of this particular chat as yet - it was more a case of it being referenced in the chats that were reported?
On the screenshots I’ve seen, there is nothing to indicate the contributors are “public school.” They come across as absolutely despicable yes, but do we actually know anything about their backgrounds? I was struck by how immature, defensive and lacking in confidence they sound actually and wonder if they’re “outsiders” in their current schools (hence the need to big themselves up online).
The sad truth is, there are boys with horrible attitudes like this in all walks of life. No school, uni or workplace is exempt, unfortunately.
