Any study in this arena will be flawed. Deeply flawed. Why?
Because, one cannot guarantee objectivity on the part of those constructing and carrying out the study. The patina of “scientific objectivity” can all too often be scrubbed away in such areas of study, and even when it cannot the results will only be accepted or rejected by others depending solely on their pre-formed notions of the truth.
Motives, conscious or unconscious, are just too strong in certain areas of life, and this is one of them.

One man did a study and hoped to find out it was OK to be brought up by homosexual parents, BUT this is what he found:
“58 percent of the children of lesbians called themselves gay, and 33 percent of the children of gay men called themselves gay.”

Which is why it’s selfish for same-sex parents to adopt, especially when so many say being gay was so tough on them.
