Sorry I don't have the skills to find it and post it here.
You just reminded me about the flak Johnny Hart took last Easter (or was it the Easter before?) when he ran a pro-Christian cartoon. I think the issue at that time was the use of a menorah in his cartoon, which was somehow construed to be anti-semitic. I doubt the liberal community will show as much indignation toward Trudeau's obvious and intentional slap at Christians.
De nada. ;-)
