You’re post #6 is absolutely correct!
NSM is part of the National Front, along with The Traditionalist Workers Party, which is not a labor organization. The third group in the National Front is League of the South, which is not about southern cuisine.
The last time the Front came out was for the White Lives Matter rally in Murfreesboro last fall.
All three of these groups turned out big for Unite The Right in Cville.
Cville is the commonality. If you don't the names of all the groups that attended Cville, and who comprises the leadership of the group, you are poorly informed. It is also helpful to know their symbols, colors, flags, etc so you can identify them when they are rioting.
