As you have probably read by now, California has joined the ranks of those few states that recognize a legal relationship between gays.  While California permits marriage, others like New Jersey provide for civil unions. 

As always, the arguments against include a statement that marriage (or union) leads to parentage and that homosexual parentage is bad parenting.  Well, dear reader I leave it to you to decide for yourself if such is the case.   Meanwhile, here are some interesting research articles on the subject from the American Psychological Association:

Seems to me that when you analyze the data presented, its men, not homosexual men, who are a problem group.  Men are overwhelmingly responsible for crime, domestic violence, and sexual abuse.  Further, the data suggests that lesbians score better than straight parents on affection, active caretaking, and parenting skills.  It isn't because they're lesbians. It's because two moms are better than one.
