You do know that the BATFE started out as a TAX agency right? Give the FedGov a power and they will find the most amazing ways to over step their bounds and expand their power.
You give one agency the kind of power you are asking for, it will be used to the benefit of whoever is in political power at the time.
And I do know that the FCC has already been charged with implementing the fairness doctrine. We're already at the bottom of your slippery slope.

You've missed the most important point: the government already has that power. The cat is already out of the bag. There can be no slippery slope. The FCC could arbitrarily re-establish the fairness doctrine today if it wants to. Remember, it was only abolished by an FCC vote, not by law. Net neutrality is not even a necessary link in that chain.
Your use of slippery slope here is a logical fallacy for several reasons. You'd do best to stop using it.
