> It’s not ok to allow easy access to hardcore pornography by minors.
I don't believe anyone here suggested that it was.
> Google and others already track us
This is not related to the discussion at hand. I already explained to you. Google does not track me on non-google sites. My state government does not track my browsing history. Neither does the federal government.
> the argument against age verification on privacy grounds is weak
You are responding with nonsense and ignoring the information I provided.
> As with most things there are tradeoffs and there is no perfect solution.
An empty platitude. The thing you are arguing for fundamentally does not work to accomplish the stated goal, although it is quite likely to accomplish other unstated goals. The "tradeoff" is a systematic loss of privacy that is likely to weaken civil liberties in the long run.
> keeping the belief that your porn viewing habits are completely anonymous vs. allowing minors unfettered access
Yet another misrepresentation. At this point I have to assume that your behavior is intentional. I'm left with the impression that you are an ideologically motivated actor who is fully aware that you don't have a leg to stand on but is attempting to sway the perception of an unseen audience anyhow.
The actual choice presented here is between a "solution" that openly invites government overreach without actually solving the stated problem versus the current status quo or possibly some alternative approach. Honestly I've yet to be convinced of the issue with the current status quo. Parental controls exist. Whitelists exist. Why can't we expect parents to do their jobs by parenting?
The mainstream social networks don't permit nudity. If you really have so little faith in your own child's judgment then whitelist Facebook, Wikipedia, and a few others and call it a day. Although I do have to wonder. Assuming they're a teenager, why do you have so little faith in their cognitive abilities?
In the end I'm reasonably certain that unfettered access to social networks is far worse for development than unfettered access to hardcore pornography. C'est la vie.
