The problem with people is that most of them truly believe that what they do, say and think is "right" in some sense.
The problem isn't believing you are right, the problem is panning empirical evidence in order to make your views sound somehow superior to those other's have.
That is my personal belief. The funny thing is that any conservative with a brain (they exist!) could probably argue his belief just as consistently and eloquently, and find as many flaws in mine as I in his.
But you did not find flaws in any conservative's argument in this post, you've simply listed your beliefs which are dissimilar to theirs. I argue that they cannot find flaws in your "beliefs" without first citing empirical evidence. No amount of eloquence can take the place of hard facts.
That said, I'd like to muster what little eloquence I have to reframe the debate and help clarify where evidence ought to be gathered.
This argument revolves around the ethics of censoring or not censoring access to certain kinds of information to certain persons. I don't care if it's censoring pornography from minors or censoring world events and critical discussion in North Korea. Censorship by definition separates a subset of people from information available in the wild, necessarily replacing said information with falsehood. Intentional deception made for personal gain against the (expected) will of the deceived is the definition of Fraud.
Thus, all Censorship is a form of Fraud.
Now I cannot speak to the morality of this until someone less lazy than I dredges up some hard facts and evidence about whether or not lying to your children about the basic nature of the world by way of censoring their access to facts outside of the home causes more psychological harm than images or viral ideas can.
Or else perhaps someone can reframe the debate if they believe I am doing it an injustice? I really do believe that pornography is nothing more than a macguffin and a red herring in a debate about whether or not parents deserve government support in shielding their children from ideas which challenge whatever the household doctrine is. Christian parents want to protect their children's eyes from the "devil" of non-christian ideas. Secular parents want to protect their children from the secular devil of sex, drugs, and rock n' roll. Chinese parents support a government which actually makes strides in shielding their children's eyes from ideas which they fear will provoke civil unrest: including democracy, Falun Gong, and any material critical of the status quo.
But unlike China we are culturally heterogeneous. Our legal definition of "pornography" is so ambiguous that we leave it up to community standards to decide what is or is not obscene. We're left in a position where one person's pornography is another persons' politically protected speech (maybe even a PETA advertisement?)
So anyone who is in favor of government managed filters has to not only provide evidence that a generation raised alongside 15+ years of unfiltered internet access is any worse off than previous generations for it, but they have to very clearly define what they seek to filter and how that material is actually harmful enough to justify being replaced by misinformation.
