I was commenting on your arguments for a filter that limits the web for other people. Like I said, you're free to limit your internet as much as you want. The problem is when you want to do it for everyone else.
That it has been technically possible for a very small portion of the population to oppress their family members further does not strike me as a good reason for making it a one click option.
If you as a parent feel that this needs to be blocked, why not do it yourself on your own network? Everyone's happy then. Nation wide filtering seems heavy handed to me.
