I would be cautious about defending those that have, from those that do not. The general public does not have the kinds of money and resources that the copyright lobby does.

For that is the first point to counter your argument: the copyright industry is not mainly looking out for artists, it is looking out for itself and its benefactors. Ask any musician what percentages of royalties they get from their song, it's a joke at this point. Live performances are the sustenance of musical artists today.

That is not to say that I don't defend the rights of artists to their work; I do. But that isn't what this battle is about, this is a battle against the same industry that finds it pertinent to send out mass blackmail letters to families, to single mothers, to depressed people. It is surely going to be one of those things that we look back on in decades to come and go "what the f--- were we thinking?"

Finally, you have to take a wider view in these matters than saying "there is some configuration of content filtering that I find acceptable," because once you have content filtering laws in place, people who you disagree with can co-opt this into a totalitarian state. You do not know who will have the keys to the kingdom come tomorrow.
