You're losing your bet. Also, you might be losing the argument by taking this conversation past the Godwin point.
But, to answer your specific question, no, I do not think it is "wrong" (which is a moral judgment) to fight against people who want to kill others.
This is a complex argument because:
1. I, due to my ancestry, would have been in the outgroup that pretty much any genocidal maniac would be targeting (including that one)
2. I would have been doing my best, back when political means were still on the table, to fight against the idea that letting the bully have his way was the most expedient manner. The whole decade would have gone quite differently if Germany had not been allowed to freely build up the means to invade neighbors willy-nilly.
3. If I had lived in Germany, eastern France, etc. would have been gone with my family way before the onslaught started. If we're letting this looming thing happen, you can have the land and my shopfront. I'm resourceful enough to set up shop elsewhere.
4. Failing (2) and (3), I'd be fighting. But thinking that fighting is the first resort is what allows you to be manipulated by a handful of rich old men who'll send you to the trenches to die.
