Regret? What I regret was having no choice as a child to do anything else. If I hadn't expressed an interest in getting baptized at 12-13, then I'd be harranged about it by my family, my peers, the entire congregation. So I did it basically due to pressue. Then they throw this "you made your dedication to Jehovah and then went back on it" in my face as an excuse to shun me when I realized at an ADULT, away from all the JW pressure, that I don't believe it.
That JW baptism means nothing to me; it was NOT a real, informed choice I made. It had nothing to do with spirituality, nothing to do with serving God; it had everything to do with the JW's using it as a control mechanism.
The only thing I regret is being raised in a cult. Which was out of my hands.
