Jest or not, comments like that can be very hurtful.
My grandmother was almost arrested and sent away by the Gestapo during WWII just because she called collaborators dirty so and sos.
And I am a lucky one as my grandmother or any other familymember did survive the war .... so many were never seen again.
That's why I reacted.
As for dogs, I have a dog too and it's cruel what people did and do with dogs or animals sometimes.
For my part, they can burn in hell for that.
But I wanted to point out that certain myths can be taken for truth.
For what I have read there were projects on both sides using animals as "living bombs" but the test results were so disappointing that they abandoned these projects almost immediately.
I do agree that Stalinism and Nazism walk hand in hand.
Stalin had the advantage of being on the Allied side (well, when Hitler decided to attack him in 1941 that is), but his reign was at least as brutal as Hitler's.
You are correct in saying that if I knew you I would know that you were joking.
But I don't know you, so I couldn't have known your true intention.
