Well if I can get annoyed by Green Peace (I hushed them once with my answer) walking out of Best Buy, I think religious groups should have the right to annoy except when it actually goes above and beyond what secular groups are allowed to do. I may not like being bothered by religious groups, but they have a right to bother within reason.
But if we walk in the light, as He is in the light, we have fellowship with one another, and the blood of Jesus, His Son, purifies us from all sin.
