Brendan Eich is very intelligent. He just happens to be wrong on this issue, in my opinion.

I self pick based on my own assessment of intellectual honesty and rigor. I have no doubt that our society will be considered similarly unenlightened a hundred years from now -- all we can hope for is some sympathy points for integrity and progress.

He still said "most" within the sub-group of reasonably intelligent people, not "all". You may disagree with that claim, but one person not fitting into "most" means nothing.

Well, "most" intelligent people in 1800's South were pro slavery. So?

As I said, you may disagree with the claim. I wasn't even personally supporting the claim in that comment, merely pointing out that it's possible for a.) the claim to be true and b.) Eich is intelligent - they aren't mutually exclusive based on his claim.

Hardly. Many of those intelligent people were slaves.
