Because that's all we get?
Don't get me wrong, the National Day of Silence is a good thing - even all 3 of my kids take part in it, but isn't silence a big part of the issue? So we get a National day for exposure to the issues, challenges, and hurts of intollerant discrimination, but silence doesn't lend voice to educating and understanding. Silence lends to keeping the secret. Does it not reinforce TG as a hush hush issue?
Wouldn't GLBT issues be better served with a National Day of GLBT Support and Understanding? A Day when schools taught specifics and offered support while teaching understanding?
