I find that bizarre because "happy holidays" used to be very prevalent among Christians. It was meant to recognize not just Christmas, but all the religious observances from Advent to Epiphany.
And "real people" have tried to point out that the concept of blessing isn't really specific to religion, let alone Christianity.
Christians getting upset about "happy holidays" is ignorant of the history of the phrase.
See, language changes over time. I thought I (or one of the other people trying) made that point around the time I brought up calling homosexuals 'gay,' and and you dropped the "mighty white of you" argument like it had burned you.
At any rate, what the words mean now is what's important. Some Christians get upset because people wish them well in ways that aren't explicitly Christian (congratulations, the fact that I didn't want to type "happy holidays/ seasons greetings/ happy Chanukah/ happy Kwanzaa/ good Yule" did give you an excuse to play dumb). Some atheists get upset because people wish them well in ways that imply not everyone is atheist.
Now, what's the functional difference between the two?
OTOH, ignoring the religious baggage of "have a blessed day"
We can't ignore what doesn't exist. Someone else simply being religious is not "religious baggage."
a phrase that came into popularity as a religious response to increasing secularism - is similarly ignorant.
Please support your claim.
My money's on a different possibility: that figuring out a point from your ranty posts in this thread is often harder than you think it is.
Oh, nice personal jab. Let me try:
I bet if you read carefully enough to realize that we're discussing a farewell, which you've called a greeting at least twice, my points would be easier to see.
Have a blessed day.
