If I prefer warm weather, but live in a cold weather climate, I still prefer warm weather.
You can't say you're a warm weather dweller despite despite choosing to live in cold weather just because you prefer warm weather. That's the point.
If there was a word for "preferring warm weather" would you argue that this word didn't apply to me?
No. But I would argue what I just stated above.
You don't become straight. You just are. It's a state of being.
Let's apply your line of reasoning to other situations and see if it is logical:
You don't become a criminal. You just are. It's a state of being. - NO
You don't become afraid heights. You just are. It's a state of being. - NO
You don't become addicted to drugs. You just are. It's a state of being - NO
You don't become a millionaire. You just are. It's a state of being - NO
Four examples of applying your reasoning to other things show it is NOT logical.
If you decide to be with a women, it's likely that you are straight. But it is possible to be with a woman and be gay.
Do you think your status is something completely independent from who you are with? So according to you, I could be gay right now even though I've only ever been with women? And someone else who is a man who has only been with men can be straight?
There's no need for a reason to explain why anyone is what they are - they are just whatever the hell they say they are, for any reason or none at all. Got it.
You're worse than I thought. Not only do you fail to grasp how your line of reasoning defies logic, but you apparently have no line of reasoning to begin with.
This is fun, but honestly, there's nowhere to go from here if you don't even have a line of reasoning.
Next you'll be saying that you're Batman and the Pope all at once. No reason - you just say so.
It must feel good inside your head when you think you can say whatever you want and it comes true.
Do you have some sort of magic genie to make that happen? If you do, maybe you should wish for some kind of sense so you can understand simple logic and reasoning.
