Bruce isn’t Dad of the year by any means, but if there’s one thing I think he’d be good at, it’d be accepting any of his children coming out as LGBTA.
Like don’t get me wrong: his original reaction might be confusion because he didn’t see it coming, or just be relaxed because he did, but after that finding out and saying “it’s fine” he would just pull up all the research to be the best support system possible.
He’s Batman- he’s not gonna half ass this shit.
Bruce making sure to keep track of all hate crime in the city (not that he wasn’t already though). Bruce making sure not to intimidate the first boy Jason brings over because he doesn’t want this kid to feel unwelcome. Bruce asking Trans!Tim about his pronouns, and offering to help with the cost of new clothes if he isn’t ready to come out to his Dad yet. Bruce telling Damian that being ace is fine and offering to introduce him to someone on the league who is ace as well. Bruce telling Harper that her girlfriend can stay at the manor until she gets a better place to stay.
Good dad Bruce.
