Good for him/her, I was pretty shocked when I saw an article about it and had to do a lot of research to actually see if it was real or not.
I remember her being on Mark Bells powercast and considering his/her story(he still identifies as both) if it makes her happy then go for it. He was one of the biggest motivations for when I got started into lifting, I remember one of the first sets of videos I watched was his bucket squats where he just squats a lot of weight for a lot of reps and ends up puking in a bucket.
When it did come out though, people were obviously being assholes about it but when Caitlyn "the vehicular manslaughterer" Jenner came out, she was so brave, such an inspiration by threatening to pull out of interviews if she didnt get the espy or whatever when the girl basketball player who died should've gotten it. Tucking your dick and calling yourself a women to later on decide that you dont feel like a women anymore doesn't make you a hero in my book. Matt talked about himself struggling with it as a child and yes he was trying to overcompensate while he was in the military and in powerlifting to do brawny man shit, feels more realistic than Bruce coming out when his daughters were getting a lot of unnecessary attention.
