What Red Line?,
I suggest forgetting being politically correct and do what you know is best for raising your children right.
The best solution which I would recommend, which is even better then "blinding them with science" would be to have their computer's networked, but put then in the family room. That way you can always monitor what they are doing. It is a much better solution then letting them have the comp in their room behind a closed door.
Take Care,
