I always thought Linus had it right when he said "there are three things I never discuss with people. Religion, Politics, and the Great Pumpkin." Well times have changed since 1965 and although I live by his statement, I also don't discuss race or sexual orientation either.
Too many on air people have gotten caught up in the current climate (call it what you want) by saying what is the now considered the "wrong" thing. It is one thing to try to be topical and edgy, but in this climate almost everything you say is going to offend someone. Pick your words carefully, and when in doubt don't. What used to be acceptable is no longer so and you may not know it until you cross the ever moving line.
And it isn't just radio, I was reading a story about a 19 year old female NASCAR Camping World Truck Series driver who had to go to the re-education camp because she used the "R" word in a podcast, as in We Todd Did, or the opposite of advancing your ignition timing.... that thing you do when using Nitrous, you pull some timing out or R word it a few degrees.
Try using "master" or "slave" in the context of hard drives in computers or hydraulics in automobiles and see the looks you get.
