Yes, people can rub us the wrong way sometimes. Me Thinks Donna Doth Protest Too Much! There is obviously something she finds a problem with but cannot express it. Maybe it's the real truth and she knows it. Yeah, I've had this kind of exchange with JW family in the past. I usually find that people who are venomous are not happy in life and have a number of issues. If she is a JW, she definitely will have the holier-than-thou and judgmental attitudes espoused by this organization. I've seen this in my JW family members. This is why I call them "Jehovans" and not Christians.
Perhaps you should have a 'stock answer' for those types. Something like... "Thank you for your email and concern. There must be some reason you are reading my website. Perhaps you can share that reason."
Everytime I comment at an online news article I leave a weblink to your site. I think it's very well done and presents the facts without appearing fanatical or extremist. Two thumbs up!
