They're not at your door for to sell cookies, they're there representing their church, and actively trying to persuade others that their church doctrine is right. When they're off duty I can give them the benefit of the doubt as individuals, but a missionary is a spokesperson for the church. Maybe when they're off duty we can toss back a few brewskis at a gay bar, but as long as they're representing the church I'm going to treat them as representatives of their church.

Given their churches conspicuous involvement in prop 8 the first thing I'm gonna want to know about their "faith" is what they've got against the expression of love and commitment of 2 individuals who happen to be of the same gender? Why do they think it's their moral obligation to take away the rights of others because of who they love.
