What the fuck part of "they'll have heard it" is snide? There are jokes in the world. Some of them get told more than others. Unitarians, more than any other religion, go out of their way to be welcoming and inviting to all faiths. This is a positive thing. However, it includes the baggage of being welcoming and inviting to everything even when things start getting silly. As self-awareness is a tenet of Unitarian Universalism, the ability to joke about said silly welcome and inviting quirkiness is pretty much a cornerstone. Such humor invariably includes poking fun at one's self and as the chicken joke is pretty much Patient Zero for all jokes, it gets told a lot. here's a whole page of them. Here's where things really go off the rails - I tell someone "they've probably heard your joke before" and I'm "snide." You, on the other hand, go off on a tear about the abolition of all religion. That makes you, what? Thoughtful?
