Is AUTHOR wrong in the post ? POST : Hey all!

My great grandma unfortunately passed away recently. She was LDS, along with many of my extended family members.

I am a trans man, though most of my family think of me as a butch lesbian. Not the problem, I don't really care. The issue comes with chapel dress code. I do not own a dress or a skirt, though my great aunt has made it very clear to my father that all "girls", myself included, must wear a dress or a skirt. 

I would be unbelievably uncomfortable if I were forced to wear something like that, and I would rather not go at all than go wearing a dress. Is it selfish of me to stay home? Should I go in a formal button-up and slacks and piss off my own family? Thank you for your judgement and any advice y'all can offer.
