My father was antifa.
He fought against Hitler.
Like most persons who actually see combat, he almost never talked about his experiences. I remember only two comments he made about it in my hearing, and both of them were spontaneous unintentional outbursts in response to scenes on television.
I recall that Bill Mauldin had a term for persons who might talk about combat. He called them “garritroopers” and described them as “too far forward to wear dress uniforms and and too far back to be shot at.”
Every American should be proudly antifa. Being “fa” is antithetical to being American.
