Jim Geraghty links to a pretty good bit on how the Internet is making it a lot easier for crazies to find each other, and how it’s probably responsible for the emergence of the new crazy in our political discourse:
Enter the Internet. The good news is, if you really want to talk about obscure bits of history, or political issues, or sports, or pop culture, chances are, thereâ€™s some online community for you. Of course, this applies to every interest, including the bad ones â€” hate groups, child pornographers, extremists of every stripe.
I don’t think there’s a good way to deal with this. Public social pressure doesn’t seem to work effectively on Internet communities, because enough of them find each other they feel comfortable in lashing back at the people criticizing them. In fact, there’s probably a great deal of feeling like persecuted outsiders that probably strengthens resolve among the adherents to whatever weirdness you want to speak of.
Humans are tribal my nature, and if your a member of the crazy tribe, the Internet has allowed you to find the rest of your tribesmen.
