If he believes it can be dangerous then it would follow that attempting to dissuade anyone from a sexual target of desire would be dangerous. It is stupid and idiotic. No where but in the realm of dumbass psychobabble would such a stupid statement be accepted. It continues to amaze me how such a sexually “liberated” group feigns as if they know nothing about sex at all.
Go read up on the "Sex Positive" agenda and teachings.
They seek to end all moral judgements over ALL sexual pairings regardless of sex, age, relation, martial status, number, or species of partner(s). They see sex as a birthright to be enjoyed by everyone at every age.
Positive.org has a "just say yes" campaign to teens questioning having sex.
The question of if homosexuality et al are "biological" or "conditional" matter not to the psychobabblists. They don't believe in a concept of "morality". It matters not what drives someone to do something, let them do it ANYWAY.
