"As if"? For the whole length of the net neutrality policy debate, the support has concentrated in the Democratic Party and the opposition has centered in the Republican Party -- not just on the FCC, but in Congress and everywhere else. The reason the Democratic majority of the FCC keeps trying to find a way to advance Open Internet principles within the framework of existing law that at best addresses the issue indirectly is because neither mostly-Democratic supporters of express FCC authority (or mandate) for net neutrality nor mostly-Republican supporters of expressly prohibiting the FCC from regulating for net neutrality have sufficient support in Congress to pass legislation incorporating those goals and get it signed into law or override a Presidential veto.

Let's rephrase it then. Net neutrality is a very reasonable idea (same way as antitrust regulations are). Why do Republicans oppose it? They like monopolistic abuses on the Internet?

It's quite simple; net neutrality represents regulations on business. Republicans are anti-(business)-regulation, believing that a completely free market will deliver the best result to consumers. Of course, in this case that disregards the reality of 80 years of telecom monopolies (and derivative companies thereof,) i.e. mammoth established players with a history of playing dirty to stomp all others out of the marketplace; it is possible that in a blank slate scenario that regulation-less competition would lead to a good result for consumers, but even that is not a foregone outcome. In short, market idealism.

That's the point. One has to be blind to reality to have such "idealism". They should know better.
