"Didn't someone nearly get done in Oxford a few years ago for insulting a Police horse? I can't seem to find a link though."
Bloody hell. Talk about a worthless pig taking a personal vendetta! Back then the term "gay" was often used by teens (and those not very far past their teens) to express a mild dislike/disappointment ("No internet till I've done my homework? Gay!"), at least around here. Only the super-sensitive or those who make Daily Mail readers look like laid-back types would get offended at someone using it.
The cop involved there clearly had an issue, and was clutching at the best straw he had to inflict some misery on a relatively innocent kid who upset the poor wee lassie.
No wonder those of us who've seen their true nature call them "pigs" - when we're being nice.
