Earlier this year, Dwyane Wade's 13 year old child came out as transgender. The announcement made big news as the child transitioned from male to female and now goes by the name "Zaya." Well, yesterday was Zaya's birthday and her stepmother Gabrielle Union sent a birthday greeting on social media.

Then, MTO News learned, actor Hill Harper slid into the pre-teen's comments and wrote "Happy birthday young man."

Many are calling the comment "disrespectful" because Zaya refers to herself as a "girl" and is asking others to do the same.

Here's what he wrote:
