Russell Moore, head of the public policy arm of the Southern Baptist Convention, said the Mozilla case signaled "very hostile times" for anyone who believes marriage should only be between a man and a woman. Eich was "hounded out of office," he said.
Episcopal Bishop Gene Robinson, who was the first openly gay bishop elected in the Anglican Communion, said in a phone interview that a corporate board has a right to take stock of how executives' views shape a companies' reputation.
But Robinson noted that Eich said his personal beliefs would not affect his performance as CEO.
Still, Robinson said he disagreed with the idea that Eich served as an example of bullying by liberals, as some conservatives claim.
"It seems to me when a society makes a determination that something is wrong, for example racial hatred, then somehow it's not intolerant to insist upon that understanding," Robinson said.
Justin Lee, founder of the Gay Christian Network, which tried to build bridges with evangelical opponents of same-sex relationships, described himself as "a passionate supporter of marriage equality." But Lee said he didn't think Eich should have left or been pressured to leave because he donated to Proposition 8.
"As much as I disagree with the donation, this is America, and I believe he has a right to support the political causes he believes in," Lee said.
