I remember while going door-to-door with my father in the mid-1950s encountering a householder who threatened to beat us up and call the police. "I'm a veteran of WW2 and a proud member of the Veterans of Foreign Wars."
My father looked at him and replied, "Well that's good. Where did you serve?"
"The Pacific in the United States Army!"
Dad calmly replied, "Well thank you for your service to our country."
"You Jehovah's Witnesses are all communists and cowards and you deserve to have your ass kicked!"
Dad looked at him and responded. "Well, if you want to kick my butt, feel free to try. But you should know that I too served in the US Army and also in Hawaii. I did not actually go to battle as I was an airplane mechanic. But that was better for me as I never wanted to kill anyone - friend or foe. Now if you still want to come down those stairs and kick my butt for trespassing or disrupting your morning, feel free to try. But accusing me of not serving in the Army isn't a good reason. However, you should know that I would never volunteer again, because Jehovah teaches us not to raise our hand against anyone, friend or foe."
The man behind the screen suddenly came out and looked my father right in the eye. "I apologize sir. While I want nothing to do with your religion, I would like to shake your hand as a fellow veteran." They shook hands and even gave each other a man-hug after that.
My father actually regretted what happened. He was afraid that Jehovah might consider his response to be "bragging about my military service."
But yeah - back in the late 1940s and early 1950s JW men took a lot of flak from veterans and families who had lost someone during the war. We kind of expected it and tried to understand where they were coming from.
