Lesbians and straights alike may have varying degrees of these resources, but turn out good kids everyday. Lesbian parents are not the norm, but as these studies show, their kids are normal. We must remember Jeff Dahmer's parents were heterosexual, so were Charles Manson's. I can't cite an example of a serial killer or other freak raised by lesbians. Sexual orientation of the parent has little to do with how children turn out.
Parents are responsible for teaching their children how to live with integrity, pride and love.
They need to know how to balance their ambition with the needs of others. They need self-confidence and the knowledge that their parents love them unconditionally. These are taught by example. That depends of the depth of character of the parent, not the sex of the person they take to bed each night. Being a heterosexual parent doesn't make you a better parent, just a more socially acceptable one.
