Animal rights charity PETA has suggested that many current English idioms carry negative associations with animal abuse and that we should change their wording to reflect awareness of animal rights. The altered animal idioms would retain the original meaning, while shedding the abusive imagery. As vegetarianism and veganism become more popular and awareness of animal rights grows, should our language change to keep up with society’s shifting attitudes? And is this a positive progression – or political correctness gone mad?
