Yes, Pandoren, you're probably right. But as of today, regardless of how much research has been done, we don't have final answers for either homosexuality or transgenderism. Far from it. But at some time in the future we'll have those answers. We'll be able then to understand, fully, all kinds of things for which we have only bits and pieces of knowledge today, some of which will be discredited in the future.

Scientific research is funny that way. Some research conclusions are proven true by succeeding research, some research conclusions go by the board. Which are reliable? Even scientists don't know until after quite some time, and many more experiments. It's a slow and grinding process. Take care!
