1) You can't fully understand antimasking politics if you can't speak of a certain antimasker's stranger ideas-- which involve sex with demons.
2) Numerous political magazines are quite willing to breach macrumor's sense of decorum-- and inserted asterisks will make urls useless, Plus you'll receive the infamous "We're not prudes, but" letter.
3) as for spam, first amendment law based on the the marketplace of ideas paradigm has been friendly to marketplace of products.
so while the neoliberal idea of complex discourse emerging out of simple intuitive rules may be romantically appealing, it doesn't really work in practice. Moreover, it's not a model that is embraced by this server's management, for good or ill.
So all these paeons to the first amendment seem naive-- it's not binding here. And if it's not binding here, why appeal to it to defend information, that if taken seriously, is likely to result in death or serious injury?
