Of course this produces the paradox of being intolerant of intolerance. Like most paradoxes it's not a problem in practice.
(Caveat: as a moral descriptivist I should point out that I believe there is not really any such thing as "right" or "wrong," just what people like and don't like. But, as shorthand, I use the same words other people use.)
I do not hate Brendan Eich. I do think he purchased what he is receiving, though.
Yeah, if he keeps looking and examining what's wrong with him he will eventually see that there really are five lights. I mean, that's all it takes right? We simply choose what to believe as it's convenient to us?
As far as "five lights", I suggest viewing "Chain of Command" from Star Trek: The Next Generation, which has a famous scene that riffs off of Orwell's 1984.

This is an issue where public opinion is changing quickly, as it often does when oppression becomes recognized as oppression. I'd recommend taking the limit of the function as yr->2020.
