Earlier quoted context omitted.
The "Brendan Eich club" is actually a small inside joke, as the sign was one of the official "features" of JSConf.eu 2011, where Brendan was an invited speaker :)
Yes, but that was seven years ago, and Things Are Different Now. (Just leafed through their twitter. I'm seeing a lot of the same clique as were involved in the node.js brouhaha last year. Is this conference really worth the fuss?)
So Brendan Eich invented JS, and then led Mozilla.
And being in the Brendan Eich Fan Club in 2011 probably was a positive thing and a cool thing for JS people.
Then much later, Brendan Eich donates $1000 to some political thing people strongly disagree with
So retroactively, being a fan of Brendan Eich means you are a homophobic hater and must be blocked?
I am quite sure this ain’t it :)
