The Religion Debate: how does it affect bums?

I have read, heard and seen a lot recently about the religion debate. Today I was reminded of an oft-forgotten side of religious activism: the crazy religious bum. They don't get paid, they don't sing well, they don't have powerful connections, they don't even get anyone to listen to them... ever. But either way they put their hours in, working for The Man, harassing people.

This afternoon I was tapped on the shoulder while at a pedestrian crossing. I turned around to have a dirty middle-aged man thrust his face in mine, open his toothless mouth and say, "Are you a catholic?". I responded with a disinterested "No.", to which he quickly stepped back as if I were the one omitting the foul stench (albeit a poorly-acted action considering he has probably done the same thing a million times).

My loosely topical tie-in is this. If the atheism push reaches bums, then what will be left for them to do? If celebrities are the modern day religious idols, then will I one day be stopped by a man saying, "Are you a Brad or Jen believer?". I pray to our lord Shane Warne that it will never come to that.
