Kazbah about the waterbirthing!

The only thing I can think of is simply to say outright that you're happy to have a respectful discussion, but you're not looking to convert and you won't tolerate being disrespected. I wouldn't be bothered if someone said that to me at the door, because we're always told to be respectful and meek - whereas if you do happen to have a 'rogue' JW, their reaction to the above comment would probably show whether or not they were inclined to being respectful. If it is an ongoing problem, you could always contact your local Kingdom Hall and explain your problem to one of the elders, they will be able to help. I truly truly hope that what these people have said is not what they intended to say, because it's hardly going to make people more willing to listen

Inanna - No words, just happy to help
