Another point I want to make about Browne: sometimes she actually does tell people good and sensible things that might actually help them. Yep, really, sometimes she does. And sometimes she says things that neither help or harm. And sometimes she says things that might only mildly harm.
For example, when I saw her perform in person, she told a woman whose son committed suicide that he didn't go to hell/come back as a lower life form because he was mentally ill and it wasn't his fault he committed suicide.
That's, ok, a pretty sensible thing to say to a grieving person. It might have brought the woman comfort and helped her and the other survivors in their loss.
However, the harm she does (like messing in murder/missing person's cases) far outweighs any help and comfort she might bring (like actually giving people good advice once in a while), anything she says that is neither particularly good or bad (telling an adult their spirit guide's names are Marsha and Jones) or anything that only mildly harms (like telling parents that their childrens' imaginary friends are actually their spirit guides and that Johnny and Jane can see them because they are "more in tune with the spirit world" because they are children.)
In fact, if she only inserted herself into a missing person's case once a year or so and if 98 percent of her doings were the other things, I'd still say it wasn't worth it and the bad would still outweigh any good that might come out of it.
Pointing to anything smart or neutral or only mildly bad she says is like pointing to the fact that Hamas does some very fine charity work (they do) and pointing out that they don't always fight their neighbors by convincing a confused teenage boy to kill himself by strapping a bomb to himself, going to a nightclub or bus, blowing himself up and, along with himself, mass murdering some teenage boys and teenage girls that neither he or his bosses have ever met in their lives.
And no, I did not compare Sylvia Browne to Hamas and do not think that Sylvia Browne is on par with Hamas.
