They sure don't fight or act like it. Their tactics are political Nazi brown shirt tactics, but far less organized and targeted. Their weapons are intimidation and inciting riots to foment fear of normal law abiding citizens to push a political agenda (Dem control). They are only rising in areas where there is enough group think to not stand up against them since they want to avoid a huge conflict. They want us to kill them one-by-one so they can play the victim card to gain media cred and use that to legitimize them as a political force. They are not forming a military and using it to conquer and hold territory like a true revolutionary force would do.
Again, I stand by my point that they know they would lose in a "hot" war. Now, we may get one anyway in November, but everyone is obviously waiting to see what's going to happen with the election I suppose.
And 60 million dead later are a testament to what happens when you dismiss the untrained amateurs.
