I'm reminded of a description of "conservative" vs "liberal" wherein it's about risk management versus experimentation.
Right now, if I'm faced with a choice between accommodating people who are doing it wrong, or challenging those people to become more, I'm going with the second option. Then again, this might not result in a viable society; or perhaps just a viable large-scale society.
To put it another way: You can view the loophole as the problem, or you can view the attitude that finds loopholes acceptable to use the problem.
> You should not treat people poorly, even if you believe that they are intolerant,
I can treat people well whom I also do not tolerate. It's just that yeah, usually, those acting intolerant are also acting like assholes.
I was giving a description of how "intolerance of intolerance" works out in practice.
It doesn't matter if you think these people are doing it wrong.
I do not believe that humans can be trusted to be given such an easy to abuse loophole, that gives them carte-blanche moral authority to act terrible to other human beings (because the the target of the abuse is "intolerant", and therefore deserve it).
It is safer to just say "no. You should not treat people poorly, even if you believe that they are intolerant, or deserve it because of some other quality".
