Only if it is cheap exploitation to send kids to lobby for their gay parents

If it's shameless when Occupy Wall Street protesters use kids, or gay parents use kids, or pro-choice women use kids...wait. That wouldn't work.  What would the pro-choice kid say? Gee, thanks for not taking me out, too?  Anyway, you get the point.  I'm not a big fan of using kids to drive home a point.  But then, I'm not a big fan all the time, not just when it's a point of view I disagree with.
