So it is advertisements where we should draw the line -- websites with advertisements should require age checks?
It clearly isn't just a singular data point that is a True or False that would include a site in the ban.
Perhaps it should be, "If I had a 12 year old daughter, do I want her to have easy access to pornography, self harm material and the ability to receive private messages from a 45 year old registered sex offender?"
I get your point - "Where is the line in the sand?" and it's a valid point but no need to argue in bad faith.
If parents are concerned about this, why let them on the Internet? Why not use parental control systems? Why not teach your children healthy sex education, how to deal with their feelings, and to tell old creeps to fuck off?
I do think the "wont somebody think of the children" arguments are in bad faith though, and I say this as a father.
