I'm not going to visit that webpage to justify their authoritarian bullshit with ad or page views. This is just run of the mill propaganda. Of course bitcoin fills the gap for hate groups. Just like it does for independent journalists when the US state dept. puts pressure on Visa/Mastercard/etc to prevent donations (remember wikileaks).
Cash isn't evil because criminals use it. And they use it because cash is useful. Bitcoin isn't evil because people with opinions you dislike use it. They use it because it's useful. Just like all the other people using bitcoin that make up the majority.
too bad you didn't read what it said since the most interesting is that they are looking to trace out members of these groups by analyzing their bitcoin transactions and have announced they'll be releasing the list soon.
For all you know I'm posting this article as a warning that "authoritarian" groups like SPLC are seeking to "out" law-abiding racists and nazis. Which of course is not true. SPLC is not a government organization and has no "authority" whatsoever over anyone.
