It's everywhere, isn't it? This abrasive presenting style, all shouty and up in peeps grills and that.
Watching some cooking school programme and it's all "listen, y'stoopid feck! What's this fuckin muck you've made?" I blame The Apprentice or something.....are they rude on Masterchef? If they are then it's a 'thing', my theory is proven and I'll write a book about it.
Where's it gonna end? Kids TV? "I said your five timestable, Georgia. God, you really are a stupid bitch, eh? Go do some colouring in or something, time waster

Anyway, what I'm saying is be polite, yeah or just fuck off
