Who was supporting the "xxx" domain registry? Certainly, it's easier to block at the browser level...
There is certainly some way to put the nudie mags "behind the counter"?
Indeed. And one suspects that is one of the factors behind a great deal of the opposition to the idea. Porn sites thrive on having IP addresses that are essentially indistinguishable from "legitimate" sites.
Perhaps, but filters have their limitations. Several years ago, I was subscribed to a provider that filtered out adult content. Worked well for the most part, but when Superbowl XXX came along, I was suddenly unable to access several sports and news website because XXX was deemed as adult content according to the web filter.
Wrong is wrong. The Bible tells us that adultry and fornacation are wrong. My own personal opionion is that the xxx domain was nothing more than a feeble attempt to sweep this under the rug so people could say that they were "cleaning" up the internet. The reality is that a XXX domain would just give the internet a legal (in the eyes of man) space to thrive, rahter then truly attempting to eliminate porn, a sin in the eyes of our heavenly father.
