You need to get a little thicker skin. This is the internet. If I were you, I'd be quite proud of yourself here. You dug up interesting enough information that most of the BBF moderators have posted in your thread--multiple times. You seem intelligent enough to carry on a technical conversation with this highly knowledgeable group. Your input is valuable to the forum and to everyone here.
However, you need to back off just a little and quit getting so defensive. We get that you are not happy with the security for BIS email. Options have been provided and anyone reading the thread gets what you are saying. The jokes about tin foil hats, etc. are just banter and you have to admit that while all of this is technically correct, for some it's just a little "chicken little-ish." It's a big deal to you and there is nothing wrong with that. It doesn't matter to most and there is nothing wrong with that either.
This is a lively group but they are good people who spend a lot of time helping people around here. So, lighten up, continue to post valuable information for people to read, accept some jabs when they are thrown your way. Every one of us here has taken plenty of jabs from other forum members. Unless someone is getting vulgar or abusive, just have fun with it. Before you know it you'll realize you somehow became part of this great group of forum members and made some friends.
