Sorry, but Newtonian physics, the particle nature of photons, and the simple existence of god are not examples of intolerance. If censorship on the basis of intolerance is, in fact, a slippery slope that is connected to these benign topics, you'll need to show how they're actually connected

Edit: oh, I see. You're one of several responders who have latched onto OC's use of the word "reasonable" and are disengenuously attacking that word outside of the actual context. Excellent example of attacking the weakest form of somebody's argument and applying the slippery-slope fallacy from there. We can do better than this, folks.
