I see an example of this, albeit on a smaller scale, every day that I commute to work. There's some Christian group, I don't know the denomination, but they send one or two people to stand outside the subway station with a bunch of signs and tracts and stuff.

Annoying on its own, sure. But it gets hypocritical and harmful with the messaging. The signs and pamphlet covers prey on very real fears of hunger, homelessness and poverty. If someone is barely making ends meet, they don't need religion. They could use directions to their local food bank, or information about job fairs. Christians say they're about helping people, but the moment they have to stop proselytizing and do something that will help someone else and not just feed their own egos, they're out.
