Several studies are out now, most recently by Mark Regnerus, which disproves the “same results” concoction of the homosexual-commissioned studies, and several have examined the data from those studies and found them to be misleading.
They are misleading if not blatantly unscientific. If you have lesbians signing up for a study where they know that their answers to a survey is evaluating their fitness as parents what do you expect the result to be? Also usually the samples are usually front loaded with the best examples not a representative sample of participants which automatically invalidates such studies. We need more studies like Mark Regnerus because he did a great job of applying a strict scientific unbiased process. He took a lot of flack for it but you can’t oppose the homosexual movement and not take flack especially if you don’t just blindly support their unscientific propaganda.
