If there were a local pod of evil, they'd stick out like a sore thumb. This is a really chill place.
Unfortunately, they're everywhere. (Edit: A second article that's more recent.) It's just, unless it's for show, you usually don't see these guys walking in broad daylight showing their colors. That kind of stuffed is usually saved for rallies.
Do me a favor. When you have a few minutes to kill sometime, browse this list of hate groups and realize there's a pattern to a lot of the names they use. A lot of them are innocuous yet often patriotic or religious sounding in nature. You see one of those names in the wild, unless you know what you're looking at, you wouldn't think twice about it. That's how a lot of these groups act, just under the radar, using coded speech and imagery to attract people in the know. It's not until they want to be known that they let themselves known, and with vague names like they run with, they're often soon forgotten unless they leave a lasting impression in your memory. Like I said, they're everywhere, and like I said elsewhere in this thread, they're often sly.
