People that perhaps couldn't afford counseling so they call her out of desparation - I can't imagine how many situations she could have totally screwed up in the 3 minutes (or less) that she gave any particular caller.
*Can't believe I'm about to defend Dr. Laura*
I remember quite clearly Dr. Laura declaring numerous times that her show is NOT therapy. People ask her opinion on a particular dilemma and she gives it. And I also remember her directing many people to more appropriate means if their problem seems to be related to more deeply seated issues.
I don't have a problem with people being critical of her. However, I'm willing to be fair in my opinions of her. Like I said before, the big change came after she converted to Judaism.
And here is the whole quote relating to homosexuals and biological errors:
"I'm sorry, hear it one more time perfectly clearly: If you're gay or a lesbian, it's a biological error that inhibits you from relating normally to the opposite sex. The fact that you are intelligent, creative and valuable is all true. The error is in your inability to relate sexually intimately, in a loving way to a member of the opposite sex it is a biological error." - Dr. Laura's Website, December 8, 1998
And this is my own opinion: Not every problem, or issue, needs months of professional therapy. Some situations are simple and can be simply dealt with.
