>Would you be willing to defuse it by instituting a policy of always saying "merry Christmas" instead of "happy holidays"?

This is nonsensical. This isn't "defusing" it, this is authoritarianism and literal capitulation to the absurd demands that are meaningless

People say "Happy holidays" now because they know some people don't celebrate Christmas and they want to be nice, friendly, and pleasant to them as well.

If you have a problem with people saying "Happy holidays" in place of "Merry Christmas" you are a fucking baby.

Don't get mad about it. That is the definition of victory for the groups creating these issues. Just ignore it and go about your day as much as possible. Don't comment about it online.

They are only industrial strength memes to create anger and distrust, thereby placing people in more manipulable mental states. You starve them by ignoring them, regardless of the merits. Most of all, don't react with anger.
