They are certain that bi-curious people should "experiment". How many people fall into the lifestyle because they are drug addicts (easy source for some drugs if only you'll have sex with "me", the same thing happens among heterosexual coke addicts)? I know of several women who went lesbian because they felt they weren't getting any attention from men and were lonely. Some turn to lesbianism to escape an abusive spouse only to realize that women can hit just as hard.
"Questioning" is short for "confused and gullible kids who are being actively recruited by paederasts into the 'gay lifestyle.'"
