scientific and psycological journals are based on science and fact, not bias. extensive work goes into creating a research journal, and if the scientific community senses bias or untrue claims (experiments where the same results cannot reproduce the same results as claimed on paper) then they do not get published or aknowledged as fact.
You should be able to work this one out for yourself quite easily.
You know from your experience that the human mind does not act the same way in every situation. Nor is it the same for every individual. Psychology can't use the usual scientific method of a repetitive experiment that returns the same results consistently. Psychology is not a real science like physics or chemistry. It's a weak observational method, only called science by name - like social science.
Anyone can have a journal published. Just because someone has "Dr." before their name, or have done extensive research doesn't make their analysis foolproof.
If you can show me proof that a child will be worse off with a loving gay parent than it would be with an abusive mother, or no parent at all (remember it has to be 100% of the time, in all observations. We're doing science here.) then I'll believe you.
