Mozilla employees did NOT support the firing of Eich. Don't use them as human shields for your assault on civility.
I say this as someone who, while living in Virgina and having never lived in California at the time prop 8 was on the ballot (I moved here a few years later), I donated to opposition to CA prop 8 and decided to not get married to my (opposite sex) partner out of solidarity with gay people who couldn't get married in our state.
I never felt that I should be or would be persecuted at Mozilla (which employed a lot of christians, and particularly Catholics), if it had become public that I funded opposition to prop 8. Nor, by the same token, did I think it was appropriate for Brendan to come under fire for funding support for it. I have sympathy for the theoretical argument that it might be difficult to work for someone with personal views incompatible with yours or your identity, but in practice Mozilla was an an extremely open and inclusive place that employed people of all kinds and treated them with respect. (In other words, a theoretical problem which wasn't in this instance a practical problem by any report I heard.)
Although I don't have any actual knowledge, if I had to speculate I would guess there were other Mozilla employees who supported prop 8 (many?). -- especially considering that prop 8 _passed_ with >52% support.
Even though I strongly disagreed with him on this subject (apparently! not that I'd have any way to know other than the media coverage of this), the incident made me feel slightly less safe and welcome there-- because clearly your lawful and constitutionally protected outside-of-work personal/political/religious views were potentially subject to scrutiny. Although not very much so, because it appeared clear to me that the events were primarily being driven by public noise, and not by some internal wrong-think witchhunt.
The CEO is the face of the company and oversees HR. Most people who objected to Eich being CEO didn't have a problem with him being CTO.
Believing different races shouldn't mix is legal. Just saying it in public will disqualify you from being CEO at most companies. Never mind funding a constitutional amendment.
That said, Mozilla works in a competitive environment. Perhaps it would have made more sense to wait for valuable employees to start leaving before dismissing their CEO. While I find his position on Prop 8 offensive, as others have pointed out, they are entitled to their beliefs.
That isn't as idle a question as you might think on first glance. Denying someone marriage rights is waaay down the list of ways voters can screw each other over through government policy. Most high income earners are in companies with co-workers who literally argue that they should be less well off.
Being anti-gay-marriage is more stupid because the upside is unclear, but we expect people in the same company to put up with bigger differences of opinion on a routine basis. Different religions have gone to war in the past. I don't think many battles have been fought over official marriage rights.
I think in programming we've learned (the hard way) that fuzzy input should be rejected. Stuff should do exactly what it says on the can. No mather how sophisticated, if a date object returns political opinion they are not parsed.
Perhaps one day we can do modular job descriptions or functional employment. Accurate task descriptions with actual specs. Well formed execution and response text. The most professional people I've worked with were already strict about what everyone's job was.

So this was far more about withholding something from a group than it was of granting something to that group.
Either way, on the total age of humanity that is an eyeblink and fortunately we are not above progressing. At least, not all of us.
It looks like pure politics, keep conservatives out and keep liberals in. His fault wasn't the donation. His fault was being outed as a conservative.
I think someone should try wearing a trump hat to work at a technology company for a week and see how long they last in the organization.
Some people like to wax poetic about getting along with people with whom you disagree. But there's a difference between disagreeing on, say, tabs vs. spaces or fiscal policy or something, and disagreeing about what sort of people do or do not deserve rights. This situation clearly falls in the latter category and attempts to conflate it with the former are very unconvincing.
