What happened to Eich should be considered at best an embarrassment to the otherwise progressive image of folks seeking sexual respect--at worst, it's a fine example of the same sort of bigotry they've fought against themselves, in some ways justifying many of the petty accusations made against their ilk.
It was not a good time to be an ally in tech.
The strict definition of bigotry is viewing other groups with suspicion, hatred, whatever. So, yes, I'm okay with being bigoted against people who kick puppies.
I think the more meaningful definition of bigotry within the context of social equality is an expression of power that flows from those with power to those without it. In this case, the one with power (rich white guy) trying to remove previously granted rights from marginalized folks (gays wanting to get married).
The fact that the rich white guy, in this case, was the newly minted CEO of a corporation that strives to bring "Internet equality" added a spice of irony to the whole thing.
To borrow your metaphor, you are not being bigoted against someone who kicks puppies. You are being bigoted against someone who isn't bigoted against people who kick puppies.
EDIT: His donation is actual discrimination based on someone's sexual identity.
Having an opinion and donating money to a cause is not remotely the same as refusing to hire LGBTQ individuals or refusing to sell/rent a house to them.
You asked if he'd engaged in actual discrimination -- by donating that money, he had. Having the opinion wasn't what people were mad about.
I was thinking more about those times that I've sat in work meetings and been asked if I objected to something and said nothing when I actually do object because I knew few others agreed with me.
Let's not get too hyperbolic here. A rich, white guy was forced out of a CEO position and he was "silenced"? He could have given interviews about his position at any tech magazine he could reach by phone. He could publish a blog post on his site. None of this suggests that he was silenced.
Let's save the powerful terms for bigger travesties is all I'm saying.
