Sorry if this inconveniences you, it's always a couple of people who ruin it for everybody.
I believe in free speech for everyone and am extremely interested in viewpoints of people who disagree with me on almost any subject. I read those kinds of replies with as much or more enjoyment than posters who agree with something I wrote.
Kind of like Will Smith in I AM LEGEND, I was accidentally followed home to Vault-Co one evening by a bunch of monsters from another forum and it has never been the same here. It's just a cascade of irrelevant posts from this same group of assholes - I would not be surprised if it is only a handful of people but they are constantly junking up the threads with ad hominem generic insults, both at me and anybody else on the thread.
I want to at least discourage these guys by making them enter a registered name. I figure that they realize that it is not worth posting if they even have to go to this much trouble because they never have anything to say. Again, sorry if this inconveniences the majority here, who usually post an invaluable series of interesting links, ideas and counterpoints that makes the central subject just a starter for a great thread. Some of the most fascinating things I have ever posted up here I got from somebody else who linked to it.
