It's fine until you are doorstepped by a Mormon or Xtian "Scientist" and politeness inhibits your slamming the door on their nonsense. It's fine until you go to a "folk club" and find every song one bloke does expects you to be joining in yelling "Halleluja". It's fine until (etc, etc, etc). In short - No it's not fine. You wave your cock about, you mostly get arrested. You wave your religion about, you mostly don't. Level playing field, what level playing field?
