Hanukkah starts at sundown on the 25th. Kwanzaa starts on the 26th. Last time I checked, people celebrate the New Year 6 days later. Fuck, some people even celebrate Festivus on the 23rd. It's a season of holidays, and people should stop considering it a problem to address it as such.
I'll still buy my friends and family Christmas presents, and put up a Christmas tree, and eat Christmas dinner. I'm not going to flip my lid over a generic phrasing, and if you do, I've got news for you: It's not "political correctness" that's ruining your Christmas spirit, it's your anal-retentive defensiveness.
