Science and truth take conviction, and if it hurts the feelings of some, then so be it. I don't live my life attempting to hurt others, but if by living my life while adhering to the principles of truth and science manages to hurt you, then I'm not sorry in the least about it. I do hope you can learn to cope with it, but I don't at all wish to take responsibility for what you can and can't deal with in your life.

Sex and Gender are the same thing. There are only two genders, and there are only two sexes. Male and female. These statements say nothing as to any sort of mental instability, hormonal balances, or general body structure. It's in reference to specific sexual organs that either do or do not exist on the human body. These statements say nothing about sexual preferences, and they do not change just because you are sad.
