Not sure what you meant by all of that ambassador, and I agree with some of it. There are all kinds of different races of human beings on this planet, with ways that a lot of people don't understand, the sad part is, that there is always someone who assumes they are more powerful than them, or they think they are more intelligent, so they try to force their views on them. Gay people do not try to force their views on anyone, but, they do hope that someone will understand them.
Now in your opinion, would you say that the people who are trying to force their views are doing it by choice? or by instinct? If everything is a choice as you claim, why would someone go out of their way to tell them that their choice is wrong? Why not just leave them alone? Do people chose to harrass? If so. Why? Where is the good free will in that?
And, what if someone suddenly decided that your choice to not be gay as you claim, was suddenly one of those choices that was constantly seen as wrong, and everyone seems out to get you. How would you feel about that? maybe they told you that you can't marry because it's against a law that they created?
Would you not marry because it is against the law?
We can be given choices as human beings like you say, but, there is always going to be someone with their thumb on top of you trying to tell you what is right and wrong, until those people no longer exist, we will mainly live as we are told.
That's why it is so hard for some people to come out.
Just look at the difference between free american women today, as compared to the 1800's, or even women struggling for equality in foreign countries while they cover their entire bodies by law. Do you really believe that they like it that way?
