Should homeowners cover the medical expense of the mailcarriers who got bitten by their dogs?

Yes because the canine is the responsibility of the owner. If that dog bites anyone it is your problem unless the dog is responding to a real threat up on your life and limb. Then it should be the dumb criminal's problem.

Mail Carriers and Dog have long histories of being mortal enemies LMAO.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
