Some interesting discussion about anti-discrimination laws here:
(The posts by xenophanes are me.)
Fundamentally, it’s irrational to force people who disagree with you to do things your way if they don’t see why it’s best — to make them go against their best judgment (also irrational to deny they have best judgment, attribute their ideas to things other than thought, and so deny the disagreement exists at all, and forcibly override them on that basis). The only rational thing to do if you want a (B) style world is persuade people, which is not at all the same as campaigning for laws to force people.
What do you think? And what do you think Popper would have said about it?
