Saying that the mere existence of another group endangers that privilege is, therefore, privileged bullshit.
Now, I'm not saying being "stealth" is bad. Many of us, for a variety of reasons (safety), have to be stealth.
Non-binary, agender, and genderfluid people exist and are valid. They are no less deserving of having their pronouns used and respected.
I still want to be asked my pronouns. Not because I'm trans, but because EVERYONE should be asked their pronouns. Because I will not accept a privilege for myself that I didn't earn.
Asking me - or any other trans person - what my pronouns are doesn't harm me.
So very few of us have platforms. That's a privilege too.
Don't throw our own community under the bus to preserve a privilege we neither need nor deserves.
