^^^ You are mixed up regarding this, similar to how you are mixed up about evolution and its theory. Evolution theory exists, but the form of evolution proposed by evolution theory doesn't.
How does this apply to gays or transsexuals? God doesn't make gays or transsexuals. God makes people. The idea that God makes gays and transsexuals is only an idea. It is the people, themselves, who turn themselves into gays or transsexuals at times, not God.

Just stop this 'free will' nonsense, aka. excuse why God fucked up his 'perfect' plan.
Our world can be deterministic or non-deterministic. There is no other choice.If the world is deterministic, you have no control over what you are going to do next. Your thoughts are driven by all the cause and effects that created thoughts in your brain. The 'choices' your brain produces are the product of C&E your brain experienced before it produced the said 'choices'. The very process of 'choosing the right option' is determined by your previous experiences and the state of your brain.
If the world is non-deterministic, there is some random process that you have no control over it. The thoughts produced by your brain are the result of C&E and some random process over which you have no control. By definition, the 'choices' your brain produces are not really yours but are determined by some random process inside or outside of your brain and the current state of your brain.
Our brain development is a cumulative process during which you have no control over this process. You did not know you were you until you were probably 2-3 years old.
Can you consciously control what happens in your dreams?
Can you consciously control your liver function?
