So, no extremism allowed....
How does that work dealing with our enemies?
At some point labelled as "hajis, sand "n-----", ragheads, skinnies, gooks, dinks, nips, Japs, krauts, Boche, Huns, rebels, bluebellies, redcoats, savages" and a host of other names considered demeaning, and intentionally so, for those people shooting at us were 'the enemy', not people.
The military isn't there for some sociology project. It is there to break things and kill people when just staring them down isn't enough: to project power against those who have decided they are the enemies of this Republic and convince them of the error of their ways.
I seriously doubt any other military is caught up in this nonsense. If you are serving you are a member of that branch, Look at your sleeve for your color, not at the arm coming out of it.
