My child is wanting to "come out" in their speech

For the last year me and my family have been struggling to come to terms with news we found out about our child. They had always struggled with their gender and severe depression. They had some extreme abdominal issues that we took them to the hospital for and they used an ultrasound along with some test and we found out after testing that they were intersex(used to be known as a hermaphrodite). We had no idea how we were just finding out when they were 17 but a lot of intersex people have different sex organs internally so it takes a long time to be diagnosed. Me and my husband took it hard. Our child didn't because they finally understood themselves and felt happy in their body. They tried to figure out what they wanted to go by since technically they could go by either gender since they have sex characteristics of both. But they just go by they and say they're gender guess. It took a long time to accept it and someone on here gave me the idea of finding a support group on Facebook because Facebook has a group for everything. Which is true. I found a Facebook group for parents of intersex children and it has really helped me and my husband. We accept and support our child. They're on their senior year and are taking speech. They have to do a call to action speech and they have decided to do their speech on why we should ban unnecessary surgeries on intersex babies because a lot of kids don't know they are intersex because they have unnecessary surgeries done as babies and are told to be raised as a boy or girl and ends up causing issues later in life. And in this speech my child wants to come out as intersex. I support my child but I don't want them to be outcasted. I'm scared this will cause bullying and ruin their senior year. But I've also raised them to use their voice. They're struggled with depression in the past. They are finally happy. I don't want that ruined.
