He was ousted in part because Mozilla is supposed to be and open and inclusive place to work,

So by "open and inclusive" that means "everyone has to have the personal opinions, even when they don't bring any of those opinions to the company?"

To clarify, I think gay people should be allowed to marry. I don't agree with the supposed position Brendan Eich has. I say "supposed" because you haven't provided any proof that this is his position.

Here's 2 great questions you should answer:

1. Should Muslims be allowed to work at Mozilla?

Islam is very anti-gay, and if you've met any Muslim immigrants, I have, they don't think the gays should marry either. Among, uh, other things. Depending on age and where they're from.

2. Should you be penalized/reprimanded/fired by your employer for having opinions they don't agree with?

Let's say this: you work for a Pakistani Muslim and in a workplace that's predominantly Middle Eastern and North African. He doesn't believe in gay marriage, you do. You donate like $50 to some LGBTQIA+ organization. Should your boss fire you?

Or let's be less controversial: you want to legalize all drugs and donate to a candidate who thinks the same. Your employer had a family member who died of a heroin overdose, and they're pretty anti-drug. Should they fire you?

Or lastly: you're a Republican. Your boss is a registered Democrat. Neither of you talk politics at work and you get along well and you do your job. Should they fire you?

hard to do that when your boss doesn’t believe you should be allowed to marry.

Was Brendan Rich going out of his way to tell any gay people at Mozilla he thinks they shouldn't marry? Was he bullying gay subordinates? If he was, yea, he should absolutely be fired. If not, it doesn't make sense to me for an employer to fire you for personal opinions you hold that don't effect your day-to-day job.
