The current purge ordered to find "extremists" seems to be a furthering of the purges Øbowel did to the officer ranks.
Getting rid of "extremists" that might not be reliable if it comes to killing citizens would make sense if the way was being prepped for just that.
So, by the administration's definition, anyone who doesn't think the existing government is working in the interests of the nation's people is an "extremist", synonymous with traitor, insurrectionist and white supremacist.
Can't we also apply that definition to Socialists or anyone else who thinks the current government isn't doing what that individual thinks it should be?
When you start a witch hunt, you first need to make sure the definition of "witch" can't also be applied to YOU!!

Additionally, the military has been forced to take lots of people that would, in times of conflict, create potential problems: Gays, Lesbians, transgenders, Muslims, etc. Now we need to weed out anyone who doesn't like the current administration because they MIGHT become violent (without any evidence)?
We had a Muslim shoot up an Army compound, yet there was never a call for Muslim bans in the military. Why are they now calling for a ban on this new group who, to my knowledge, hasn't negatively affected the military in any way, shape or form?
Just more fear mongering to divide the nation and paint their political opponents as violent.
