Fair enough. In the end, I'm not going to go around demanding that people use a definition if it would endanger them or subject them to harassment. I'm still going to use a concrete definition for when I need to communicate and as such believe it is necessary for the purpose of two way communication on say, trans issues with a cis ally. But none of that means you have to use it.

I still don't get the ethereal Meaning thing and how that makes any sense for the purposes you're putting it to. But it is perfectly reasonable to put the safety and well being of human beings over linguistics. So I guess that concludes things.
