Common sense is one. Probably everyone you ever ask the question of "Can you decide you want to be attracted to the opposite sex of what you're attracted to now?" is another.
Common sense suggests sexuality is dictated by action, so your line of reasoning actually supports my argument, not yours.
What people think doesn't do anything to support your point of view, never mind that you have no idea what "everyone you ever ask" might say in response to that question.
Yes, I understand you define them that way in regards to sexuality.
No, that's not what I said.
I said I recognize that people are defined by what they do, not by attraction, feelings, or what they say they are.
Logical reasoning defines them this way. I choose to recognize logical reasoning trumps over propaganda based lies.
In the meantime, you and others deny logical reasoning because you are either deliberately putting forth lies and propaganda or you can't think critically enough to see past them.
So you're either a liar or a fool - pick one.
