I’m fine with returning him to active duty, even if it that active duty is just a smidge this side of “constructive termination”. If he commits treason while on active duty I’m fine with a court martial and a hanging. I’m still not fine with having previously been in the military restricting his right to speak. (that said if his speech actually is actionable as a civilian, I’m all for charging him, but as a criminal matter not a military one)
That said to me this has far more to do with establishing a president of overreach. If Flynn chokes to death on a chicken bone I won’t shed a tear. If they do recall him to service and execute him I won’t be upset that he was punished, just when that same power is used some other year against someone who is actually innocent.
I also wouldn’t donate to the ACLU to defend Flynn (I do donate to the ACLU on general principals, and wouldn’t stop doing so, but a “we need an extra $1 to defend Flynn” wouldn’t get me to reach into my wallet).
