AITA for making my father’s transition public after he blamed me for my son getting bullied?

I (36M) have a 13-year-old son who recently started getting bullied at school. It escalated to the point where he came home crying, saying kids were calling him “the tranny’s kid.” I was confused—until he told me they were talking about my father.

My dad (now 58F) came out as transgender last year and began transitioning. While I supported her, I did warn that she needed to consider how this would affect everyone, including her grandkids. She said she didn’t care about “societal expectations.”

Now, my son is suffering for it. He begged me to talk to his school, but what could I say? That kids should magically stop being cruel?

When I confronted my father about it, she went on a rant about how “this is what real oppression looks like” and how my son should “use this as a lesson in tolerance.” That was the last straw.

So, I went on Facebook and made a post saying:

"For everyone asking—yes, my father is now a woman. I support her choice, but I do NOT support her ignoring how this affects my son. If you see him upset, maybe don’t ask him why kids are harassing him, and instead ask why a grown adult refused to consider how their actions impact their own family."

All hell broke loose. My dad called me in tears saying I just “outed her” to the whole community, that she wasn’t ready to be so public yet. I told her, “You weren’t ready? But you were ready to let my son be tormented?”

Now I’m being called transphobic by her friends, my siblings are divided, and my son just wants everything to go back to normal.

AITA?
