I'd consider this very "low road" behavior.
I'll fight the fight by being honest, upstanding, factual, calm, rational and "professional" in deed and word.
The enemy can make fools of themselves. They're only playing for the choir and the genuine "middle-ground" are unimpressed.
Still happily answering to the call-sign Peetza.
The problem, as you so eloquently put it, is choice.
He is no fool who gives what he can not keep to gain what he can not lose.
