I agree .. it doesn't matter what color your skin is, or whatever minority group you are from, what matters are your choices, specifically how you spend your precious, precious time.
I'm gay, and am bootstrapping my own startup. I have never wondered how many other startup founders are gay .. because that's not what it's about!
Nitpick: You can hide that fact when its inconvenient.
I've found it rarely even comes up, unless you're talking about family with coworkers or something, and by that point you're probably already hired/funded/'in' and will have already overcome any potential stereotypes that someone might otherwise have had about you.
