Nothing is static. Which is another danger playing the label game.
Okay, there are periods of stasis, and periods of change. Change isn't a constant, and sexuality can change, over your lifetime. There's also the myth that "You're born that way." Okay, some people are, or at least start feeling different around age 6 (On average) while others change over time...
Labels are just how we think, and aren't bad, in and of themselves. "Can you hand me that..."
"What? Apple, pipe wrench, quart of KY?"
That's what labels are for, but we have assumptions that an apple is sweet, and not sour. The pipe wrench isn't for turning my tobacco pipe, and KY isn't for medical examinations.
Ignorance is bad, but unavoidable, because nobody can know it all. Labels are just neutral. There's good labels, and bad labels, but none truly describes what they refer to in totality. They're just shorthand, so we know whether they're pointing to the pipe wrench, or the apple.
