They still want that writing to be relevant to what they do look for. We understand it’s important to you. But just being gay isn’t an “it” or something they feel they need to know. Lots of kids aren’t hetero, lots of their co-workers, as well. Many who had a coonservative background, too. It’s not uncommon.
They’re looking for traits, some factor and action that changed you for the better (meaning impact on others, new/valid responsibilities taken on, etc.) Not just, well, “You should know this about me, it’s important to me.”
There are kids who can write this. But there’s got to be an arc of some sort. Show, not just tell. Some kids get involved in quite valid ways, with teens at risk, at shelters, in local advocacy, things that enhance their maturity, perspective and engagement (not just in the hs.) Takes us back to the idea that this revelation needs to show the traits they want. And not that you feel two-faced or uncomfortably pressured.
