I agree with Selene. Stop listening to crooks. I personally don't believe in Heaven or Hell, God and Satan, so the only thing that bothers me in such claims is the insult that they throw at Michael when they suggest he was a bad person (without personally knowing him). So when I hear that I have every right to call out these people as crooks and religious nuts, no matter whose sensibilities might be hurt. They have hurt those who love Michael, first.
Remember these are also the kind of people who claim everyone from Gandhi to your atheist neighbor are in Hell (and basically the majority of mankind!!!!) no matter how many people they have helped in their lives, just because they did not believe in the same god as they did. Religious extremism isn't just something that Islam has. It's equally present in Christianity.
I also think this type of people are attention seekers. They seek fame within the Christian community with claims such as this. I bet if someone would get a chance to thoroughly examine this woman's medical history it would turn out she was never dead. Let alone for 23 hours.
