Then how do you account for families that have both homosexual and heterosexual children? Rosie and bro were brought up in the same family, and therefore maybe the one parent's lack of love or attention could have been involved in their sexual orientation. When an offspring does not receive the love from a parent, then they have the tendency of seeking love from another person of that same sex to compensate for the lack from that parent. Rosie may not have received the love she desired from her mother, and bro might not have received love from his father, and so to fill that gap, they sought out people of the same sex to fulfill that love they didn't receive from that particular parent.
Exactly. Anyone who's ever seen the classic effeminate, lisping, mincing, man-obsessed neurotic homosexual knows that what they're actually seeing is the reflection of the guy's mother (assuming, of course, that child wasn't adopted in San Francisco, NY, Boston, etc. by two classic effeminate, lisping, mincing, man-obsessed neurotic homosexuals). If that mother's behavior could produce one gay son, it could just as easily produce two (or a Lesbian, for that matter).
