I'm going to call out my transgender friend after she questioned my national identity
Are you mad at your friend for questioning that?
Yes. I'm not against my transgender friend but I just don't want to hear about it anymore.
It's inappropriate to ask about someone's national identity since it's tied to one's immigration status and can be used to discriminate against them. However you shouldn't call out your friend if she asked you that question without any malicious intent. You can talk to her privately instead and tell her than you prefer to keep that information private since it's sensitive information and can be used against you.
I'm going to tell her that.
I'm glad that you are going to have a chat with her to sort this all out. I hope it goes well.
