If anyone wishes me happiness I'm all for it. If you're Jewish you can wish me Happy Hannukah, if you're Christian wish me Merry Christmas, if you don't know what you are, wish me Seasons Greetings. It's all good. It seems to me that Political Correctness should be to have a little diplomacy, politeness and good manners.
BTW, here's wishing everyone a very Merry Christmas!
