Underhanded?

The Jehovah's Witnesses had a literature stand set up on the street today. I stopped and talked to them briefly, and they gave me a leaflet with an invitation to one of their services. Some religious groups use Easter as an opportunity to do outreach, because some unchurched people will be thinking about the meaning of Easter. In the Jehovah's Witnesses' case, this is disingenuous, because they don't observe Easter.
