How would you like best to be asked out?
I think this is polite and respectful: "Hi. My name is AuldSoul. I've noticed you around and I know you are a devout JW. I used to be a JW. Have you ever thought of coming out? I'd be happy to help you."
OHHHH! You mean like on a date! Then a variation on the preceding: "Hi. My name is AuldSoul. I've noticed you around and I know you are NOT a devout JW. I used to be a JW, and I am not really interested in pursuing a relationship with a current cult member. If you aren't too put off by former cult members, would you like to go to the movies with me sometime?"
Respectfully,
AuldSoul
