XXY Manifesto

I wrote the XXY Manifesto because many XXY boys, men, and their parents have adopted negative, oppressive medical standards as part of their personal identity. For instance, I saw a custom T-shirt where the guy wore a message that read “XXY = Klinefelter Syndrome” – but it’s simply not true.

Why label yourself with a syndrome instead of living as a true equal? I see this all the time. It’s similar in nature to self-deprecating humor, undermining the self in the service of false standards that hold people back.

The XXY Manifesto exists to inspire us all to live to our greatest potential. Download it below, and please help spread the word by sharing this with your friends on social media.

5. Attack medical misinformation as if our lives depend on it. (They do.)
