The problem (on both sides of the argument) is that there's conflation of the website-ISP relationship (i.e. should Comcast be allowed to throttle services/make "fast lanes" for certain services) and the provider-provider relationship (i.e. should Comcast allow other providers to get direct connection into their backbone?)
The agreements between Comcast and Netflix fall into the latter, but because people only think of Netflix as 'a bunch of servers connected to the internet', many don't realize that Netflix/Cogent has stuff inside the backbone, which is a different discussion.
A (shitty) analogy would be the difference between the post office charging me more in stamps depending on who I was when I want to send a letter (net neutrality), and the USPS charging me for the right to be able to have my own stuff inside the post-offices themselves and dropping stuff directly into the trucks.
