It is true that they can sense it. You can't let them have the upper hand. You can't give them the impression that you're weak - that you really want what they have, but that you're not as strong or worthy as them. They're condescending. They think we need/want their help. They think "the brothers" could help us if we would only allow it.
You have to keep reminding yourself that they wouldn't stand a chance against us in a debate. That's why they run from such. JWs don't even know/understand their own doctrine. The org is trying to hide its own history. JWs should be disturbed by their own history - that is, if they knew about it, but most don't. JWs live in a delusion. They are part of a group that virtually idolizes seven men (actually, more) and an organization and a website. The org' seems to be like a corporation. It has become cheap and shallow. It is cartoonish.
The next time a situation like that arises, you can just completely ignore the JW, reminding yourself of the above. Since you DA'd, I doubt that JWs will attempt to interact with you, but if they do, be strong. You have the upper hand. DO NOT FEAR. Do not give the impression that you want/need them. If they look at you in disgust, then you can do the same to them, for you have ample reason to be disgusted with them and the org.
JW: "Peony, would you like for us to send the elders by to see you?"
Peony: "Oh, no thanks, I clean my own windows. Besides, JWs charge too much."
JW: "Oh, I meant to help you spiritually."
Peony: "Are you kidding? OMG, no. You all are the ones who need help. JWs are clueless. Please check out the website www.JWfacts.com."
The scenario immediately above is more intended for you to just think about to give you confidence, not to actually be used (unless the JW's manner calls for it). If a JW sincerely tries to help, you could show strength and in a dignified manner be reasonable and point to an issue or two that disturbs you about JWdom. Maybe you could plant some seeds. But just don't show weakness or give them the impression that they're right and you need them.
Also, I'd like to mention that I do understand your feelings. I get disturbed when I see them, too, but because I know they're clueless, yet think something's wrong with me. That I find to be very unjust.
