I hope those suggesting rude and sometimes dangerous methods of dismissing unwanted witnesses were just kidding. Lord have mercy, seems to me there is enough hate in the world without perpetuating it.
Funny thing is , some believe in freedom of religion as long as it's theirs.
I recently had a couple who came to my door for a religion I used to "study" with and I just let them know that "this was a Christian household and I wasn't interested" and that was that. They didn't attempt to dispute with me cuz I wouldn't have indulged them. At my age I've heard and read plenty. Not only is my mind made up but it is closed on the matter too.
If you don't try to proselytize me, I won"t try to proselytize you. All you need to say is "I'm not interested" and close the door.
Though I must confess my sense of humor got the better of me when I read a posters sign on the gate that read. "We found Jesus , he was behind the couch".
or the one that says, "We found Jesus , we like our vacuum and gave at the office".
There's no reason to be rude, unless they ask for it by being pushy, then I've been known to push back. Like the time they were talking to my young son and he had a pamphlet in his hand then I got mad and they ran down the side walk.
Of course as usual this more than I think the op asked for.
