Don't you think a group calling for Jihad and America's death is a threat? People with the same twisted ideology are the ones who conducted 9/11. So I'd say they have a proven track record.
I mean, yeah. Contrary to popular belief, I am not anti-free speech. But there's nothing to indicate the people in your article had the ability or means to back up the threat. There's nothing to indicate they were training in tactics designed to hurt people.
Also, I am not even anti-militia (though I am also not pro-militia). If people want to train as if they were in the military, all the more power to them. I am even skeptical of the Maine legislation as it was written, since I think shooting ranges and defensive gun training is perfectly legitimate.
But combine specific threats against community members with training and means to carry out that threat, and I think there's a justification for the community to work to secure the rights of "life, liberty, and the pursuit of happiness" for those under threat.
Do you not see what the Maine white supremacists are doing as threatening? People with that twisted ideology have also carried out some horrific violence.
Also, please note that the post I directed you to reread also brought up a scenario that included Islamic terrorism as a potential threat. That was alongside ecoterrorism (which I may be a bit more sympathetic to). I find it...concerning that some people find Jihadist chanting as more of a threat than Nazi chanting from a group training in paramilitary tactics.
