Personally, I think there is a fear on both sides. BAC are afraid of being decieved by JWs. JWs are afraid of BAC for the same reason.
I don't think you can accurately say that BAC's do not reach people door to door. There is more than one way to preach door to door. As JWs often point out, today's society can be wicked and dangerous. Many people will not open their doors to strangers, so the gospel has to be brought to them in alternative ways. (Television, Radio, Mail, Phone, Computer, etc...) The gospel was also preached in temples and public areas (I think in Acts 17). Are we to say it wasn't done correctly, because a different method was employed in those instances?
Rarely do I ever hear any of my BAC friends say anything at all negative about JWs. Usually they commend them for certain aspects, even if they don't agree with their beliefs. My JW friends, on the other hand, take every opportunity to bash any religion other than their own. They have NOTHING good to say about them. They over look the many good things that other religions are doing. (Charity work, etc...) They know all about the history of other religions and why they are so wrong. But they know precious little about their own. If you look in to the history and beginnings of the WTS, you may understand better why Christians are leary of JWs.
BAC's don't spend near the time bashing JWs as the WTS would have you believe. I have been in many churches and the subject of the WTS rarely comes up. When it does, it is usually because a frantic and confused relative has been cut off from their JW loved one. I have not had one conversation yet with my JW friends in which they have not made it a point to hatefully slam some other religion, however.
This is just an observation from my point of view. I am not a JW and never have been. I don't hate JWs. I do question how they can spend so much time studying other religions with out giving much thought to looking deeper in to the history of their own, though.
