That’s just another popular misconception, Rook.
A lot of studies have been done trying to determine if there’s a link between dysfunctional parenting and homosexuality, and no strong link has been found. Think about it for a minute. If dysfunctional families automatically resulted in homosexual children, then 100% of the children of certain families would be homosexual, and other types of families would never produce a single homosexual. But that’s not the case. Homosexuals come randomly and evenly from all types of backgrounds, all types of families, all social classes, and all cultures.
The theory that you’re quoting originally comes from Sigmund Freud, back 70 or 80 years ago. He was trying to speculate on the nature of homosexuality, and he came up with his theory only as a hypothesis. It was only based on observation of a small sub-class of homosexuals–those who were mentally ill and in therapy at the turn of the last century.
Modern research does not support Freud’s theory as applied to the entire homosexual community, and it is largely discounted today by the scientific community. The only place theories like that retain any currency is in those religion-based websites and publications which don’t mind pushing outdated and skewed research in order to promote an anti-gay agenda.
According to everything I’ve heard and read, homosexuals appear with roughly the same frequency in healthy families, and in dysfunctional families, and in all families in between. Even children raised by two lesbians or two gay men demonstrate the same frequency of homosexuality as children raised by straight parents. From all the evidence at hand, the quality or type of parenting seems to have little or no influence on the occurrence of homosexuality.
According to one recent study, there does seem to be a link between lesbianism and a strong, intellectual, independent same-sex parent (which is the exact opposite of the theory you quoted, by the way). But that same study doesn’t find any link at all between gay men and the quality of parenting. And other studies have found substantial evidence for genetic causation.
In short, there isn’t any justification for pointing the finger at the quality of parenting. At best, parenting is only one of many influences on a child’s sexual identity.
Why would Freud’s theory apply to homosexuality in the animal kingdom? That doesn’t even make sense. Bad parenting by animals?
