According to the Pew Research Center's polling, most Americans are in favor of marriage equality, and have been since 2011: http://www.pewforum.org/2014/09/24/graphics-slideshow-changi...

There's a difference between being in favour of something and being offended by anyone who disagrees.

There's a difference between being offended at disagreement and being offended at someone who took action to remove your rights.

Which doesn't mean in the slightest that whomever disagrees with the majority deserves to be kicked out of the company he founded.

Good thing he wasn't kicked out then, and instead voluntarily resigned, right?

He resigned because of the clamour of the bullies, and because he didn't want the Mozilla Foundation to get hurt with it.

Exactly! He managed to put the company's best interests before his own, and chose to resign. But he wasn't fired: the Mozilla board did not ask for his resignation. He could have stayed if he wanted to.
