This is by no means a critcism of this comic, because it’s funny, but… Why is finding “a non-offensive generic holiday card” even a real enough problem that it needs to be a subject for humor? None of this is brain surgery: You send Christmas cards to Christians. You send Chanukah cards to Jews. If you believe your Hindu, Muslim, Buddhist and atheist friends will feel slighted, you can always find a New Year’s card or something non-holiday-related.
If this is too much trouble for you, then don’t send cards. If you don’t know your friends well enough to know whether they’re Christian, they probably shouldn’t be on your list.
And Ms. Montague-Reyes is right: A card like this respects nobody’s holiday.
