Really? Then why can't he play with the tractor while wearing a pink tutu? Huh? Explain that one, miss know it all mommy. These kids will turn out "aggressive" when they're on every medication in the world frying their minds because they're so confused. Yes, he will get teased which will turn him more aggressive.
I can see him being suicidal or a prancing flamer. Hopefully he will outgrow his parents mental instability.
