The ranks of the White Nationalists who marched in Charlottesville, are weak, vulnerable, low intelligence, dysfunctional, paranoid, obsessive, depressed individuals, who find a twisted calling and a brotherhood to vent all the wrongs done to them or their family.
Weapons and the 2nd Amendment gives them authority and legitimacy. They get hooked over the Internet. And for the first time in their lives, they get positive feedback from their new club members. And now, they feel that a US President has their back.
None of them would last 48 hours in a US military combat unit. Like Trump, they are blowhards. They are pussies. If they brought their act to Detroit, or Cleveland, or Philadelphia, their bodies would never be seen again.
