For those who supported this, I am curious for your answers to these questions: 1) Should Mozilla deny employment to programmers who are against gay marriage?

For those who supported this, I am curious for your answers to these questions: 1) Should Mozilla deny employment to programmers who are against gay marriage? Like your average programmer from Arab and Muslim countries. 2) If said programmer is allowed to be employed by Mozilla, are they also allowed to be promoted sometime after being hired? 3) If they are allowed to be promoted, what level should be the limit of promotion? Since obviously you disagree with them being CEO.
