I'll summarize:
The contest organizers don't accept trans women (AKA assigned male at birth, transitioned to female)
This means that they are being transphobic, they aren't treating trans women as women.
The person in the article is the opposite, assigned female at birth and transitioned to male. AKA a trans man.
This person is considered a woman by the beauty contest despite identifying as male.
He entered the beauty contest as a form of protest and to bring attention to the blatant transphobia.
