Suppose a world where there are your vocal cords, pens, and printing presses. The sort of world that existed when these "free speech" ideas where first being seriously considered.

Should you be under fire if you sell a printing press to an unsavory bunch of people?

How many levels of "providing a platform" can we go through before we no longer vilify people? We do business with companies (our ISPs) who do business with companies (other ISPs) who does business with a company (8chan's ISP) who does business with a company (8chan's host) who does business with a company (8chan) which is used by extremists. How deep does this go?

Alternate question: Should we bust newspapers for pimping?
