When someone requires that I treat them as if they were of the other gender, they are demanding that i participate in their delusions. You are under no obligation to act as if someone’s testimony is true. You may reject it and carry on living as you see fit.
I couldn’t care less what sex someone wants to pretend to. I only object to their delusions being foisted on me in such a manner as requiring me to behave contrary to my understanding.
You, however, object to me even stating the truth as I see it. What are you so afraid of?
Adults don’t need to feel threatened by someone else holding a different viewpoint from them. They only need require that they can live their life without regard to viewpoints they don’t accept.
