When asked why I am the way I am, I have often responded by asking, "What is your favorite color?"
Whatever the reply I respond with, "Why that color?"
And I get a lot of answers. Then I say, "I don't get it."
And I get a lot more explanations. And I keep saying, "I don't get it"... until they do.
Maybe if we knew exactly how the human mind works and how each tiny bit of information introduced through the senses is processed and how each of those bits affect the person individually and collectively, we might begin to come close to explaining why we are the way we are in a logical and understandable way. But we're a long way from that.
Rather than relying on your logic making sense to someone else, you could instead just accept. A bee lands on you and stings you for no apparent reason. You could spend hours, days, weeks, months or a lifetime trying to figure out what caused the bee to sting you. Or you could just say, "It's a bee. It stung me," and move on.
The problem with trying to use pure logic to win an argument is you have to have enough knowledge about the subject that you can apply logic in a sufficiently compelling way so as to convince your opponents they are wrong and you are right. And most people have their own definition of logic. "Being unhappy with your birth gender just isn't logical." To some, that's all it takes. Tough sell.
That's why the concept of acceptance appealed to me. I've always relied on logic as my guide. In this case, I found it most logical to simply accept who I am and accept others for who they are. Then I can live my life in peace.
