But if you believe there is nothing essential about gender, (which is what a lot of feminists on these boards seem to believe), then referring to the pronoun or name of choice is no cost to you - because you know it is just about a name or pronoun and is no more meaningful than that.
You're not conferring on them any status because you know, and truly believe that this is impossible anyway - given that any man or woman can be anything at all.
So all you are doing is showing a measure of respect for a chosen name and a set of pronouns.
On the contrary, using a pronoun that mis-sexes the person comes at a cost to me. It implies I buy into this ideology and respect the right of others to dictate how I use the most basic words in English.
I read this quote by Theodore Dalrymple recently, which I think applies to coerced pronouning:
“Political correctness is communist propaganda writ small. In my study of Communist societies, I came to the conclusion that the purpose of Communist propaganda was not to persuade or convince, nor to inform, but to humiliate; and therefore, the less it corresponded to reality the better. When people are forced to remain silent when they are being told the most obvious lies, or even worse when they are forced to repeat the lies themselves, they lose once and for all their sense of probity. To assent to obvious lies is to co-operate with evil, and in some small way to become evil oneself. One’s standing to resist anything is thus eroded, and even destroyed. A society of emasculated liars is easy to control. I think if you examine political correctness, it has the same effect and is intended to.”
In my experience of living in a communist country, this was true. I got into trouble as a teen because I didn't want to assent to what I had come to realise were obvious lies and I naively thought that truth was necessary for our country to be better.
(As a communist state, mind, I was a true believer. I just thought we'd do communism better without the lies and lip service. What can I say, I was a teenager and had no idea what was really going on in my country.)
And I have educated myself about queer theory, the doctrine of gender identity and and the lives of transgender people, their struggles, their needs and their beliefs about themselves.
I have concluded that implementing the doctrine of gender identity is not necessary to help transgender people live safe and happy lives. Because the doctrine of gender identity is evil in my view and implementing it will harm not just society and female people in particular, but also children and transgender people themselves.
I believe that demanding that I use preferred pronouns or state my own is asking me to co-operate with evil and for me to become, in a small way, evil myself by endorsing the ideology and contributing to the social pressure on non-believers to participate in the lie.
