You know, more and more I am starting to think PC speech really stands for Polite Company Speech -the sort of speech (grand)mother insisted on. And a large part of society is still trying to rebel against her. To a point I now feel that when questioning a man’s courage it would sting more to say “You, sir, are a coward” than “You fucking pussy” would.
Perhaps it makes sense that we are now getting this PCness, since vulgarity is so common place, the ‘new’ rebelling is pretty much a slap to the back of the head with the warning “Language!”
