Sorry, James Dobson, but your assertion that lesbian parents will screw up their kids isn't true.
In fact, a recent study shows kids that have two moms may actually be better adjusted than their peers — that's especially true if they didn't have a daddy. Read it and weep: http://www.msnbc.msn.com/id/37553783/ns/health-kids_and_parenting/
On the other hand, casual observation would suggest that having straight, cultishly-Christian parents can screw you up. Or even threaten your health.
Remember Colleen Hauser, who fled across the country with her cancer-stricken 13-year-old son, Danny, last year? She was trying to avoid giving him the chemo that would save his life, because Colleen thought God was going to cure Danny. In the end, the Hausers were found and doctors saved Danny's life.
