I am with you on misuse of the word “gay”. I used to get upset about people using it like that, but looks like the media brainwashing had an effect on me too. That said, sorry to tell you but most people these days don’t even know it once meant happy. If you say “I met a gay man today” anyone under 70 will assume you mean a homosexual.
I'm on old fuddy-duddy (yes, now well over 70) and since Christmas is but two months in the past, I recall the time when Deck the Halls didn't invoke gales of laughter with the lines, "Don we now out gay apparel". And sometimes for shock value here on Free Republic, I mention that I was in a gay marriage for 40+ years until my lovely wife passed away.
