How might a Free Thinker deal with such a statement which constitutes a presumption of a specific religious belief?  If we are rude, arrogant, or too emotional, we don’t enhance our position.

My current reply is: “Thank you, but that is not a holiday which I chose to celebrate.”

Goal: To politely indicate that not everyone has those beliefs.

Reactions: Embarrassed; apologetic; and contrite.

“Thank you…” – polite.

“…I chose to celebrate” – individual choice.

Result: Politely indicated that not everyone has those beliefs.
