The irony of using intolerance of anti-Semitism as a defense of the virtues of intolerance while so many here are trashing the sincerely held religious beliefs of the conservatives[1] should not be lost on us. If "intolerance against assholes is often virtuous", perhaps it the intolerant left as well as the intolerant right that the rest of us should not be tolerating, arf arf.
A man takes a dump in the communal pool and is asked to leave. The man comes back the next day and shits again. Story repeats until the man is banned. The man cries about intolerance and censorship. The man gets backed up by internet's peanut gallery. Because oh gosh those darn liberal pool operators are hypocrites that don't even tolerate natural bodily functions!
It's wild how many people can't seem to wrap their heads around the very simple framing of tolerance as a contract. We have chosen to engage in tolerance, which means that we will BOTH be tolerant of each other. Once you engage in intolerance, the contract is broken. We are now not BOTH tolerant, so the contract of 'tolerance' has become void. It's not that I can't tolerate intolerance. It's that the logical structure of 'tolerance' is terminated when any of the active parties stop participating. I'm not 'intolerant of your intolerance'; I'm no longer affording you coverage of the contract that you voided until you engage in earnest action toward repairing that relationship, at which point you will be eligible for reinstatement to the contract parties.
Anyway, your pool analogy is great! It's just frustrating that people even need it. =/
