ricsa - When you are with other JW's, what you believe seems right and normal. But as you said, when it comes to "worldly" people, you know that it will seem weird or strange to them what you believe in. You could liken JW's to being a group like the Amish. They are isolated in a certain location and keep to themselves for the most part.
JW's are isolated from the rest of Christianity and world, by not celebrating birthdays (or any other holidays) it used to be NO blood for transfusions but now they take fractions and other things. The most isolating is the view that all others that aren't witnesses, are bad, wicked, have a bad heart and that goes for close family members and relatives. So the religion makes it a "us" against "them"
Growing up in the religion, I wasn't supposed to have any friends at school only those that went to the meetings. No outside activities. It's very effective in making you depend on whatever relationships you have at the hall. Now that I am out, I have no friends. So unlike those that keep in touch with childhood friends or ones they met in college, I have to make new ones. Too bad I'm not easy to get along with anymore. Makes it hard.
