Just live and let live. If they pop me a brochure about their church in their hands, I just accept it, let the guy go on with his work and drop the brochure in the nearest bin. I got one from Scientology Church recently, I must admit out of curiosity I peeked into it before throwing it away. I dont have a problem with street preachers, just let them do their thing and ignore them.
I have once encountered a nice one in Belfast, Northern Ireland. I passed a street and on the corner was a catholic priest preaching. I politely refused when he asked me for a prayer. I walked on, and at the other end of the same street a protestant preacher was speaking. That is what I call competition!
