> At the time Eich made that donation, every major Democratic presidential candidate (including Clinton and Obama) were ALSO publicly opposed to marriage equality. So it seemed like extreme mental gymnastics to put a "hate speech" label on Eich.

No, the extreme mental gymnastics here involve thinking that hate speech can be defined by looking at the content of Clinton and Obama's campaign speeches.

The ouster came six years after his donation. The only way that could be characterized as "long ago" is by the use of extreme mental gymnastics.

Anyway, donating to Proposition 8 is equivalent to making the statement "I will actively work to take other people's rights away, even though it will never affect me". Is it any surprise that he was ousted? It was a disaster for Mozilla to associate with him.
