The problem with all of these studies of children raised by gay parents is that nearly all of the researchers who have conducted them have been homosexual themselves, and the issue of bias which would inevitabilty be brought up had the researchers been heterosexual and/or culturally conservative is never addressed.
For examples, read through the following replies in Scripter's Homosexual Agenda: Categorical Index of Links (Revision 1.1) thread:
Reply 272: An excerpt from "Are children of gay parents worse off?"
Reply 283: An excerpt from "Professional Pediatrics Group Discourages Gay Parenting"
Reply 284: "Documenting the pro-homosexual activism in the American Academy of Pediatrics"
There is a mine of information here on FR, and anyone who persists in remaining ill-informed about the real nature of homosexuality and its agenda will continue to get hassled by ME!
Thanks, EdReform!
