Three words that can get you damned

I've been a bit unsure about using the phrase "call to action" as a quick way of describing things like a poster at a bus stop asking "Where were you happiest to arrive and why?"

Partly because it feels like one of those phrases it's easy to repeat so often it becomes meaningless, and partly because it makes me think of marketing.

But then I had look on wikipedia and found that Call to Action is also a left wing Catholic group in the US, which if you join you automatically get excommunicated by the Bishop of Nebraska - no trial, no right of appeal, straight to Hell.

Three words that can get you damned can't be all bad.
