Are you kidding about this? The axis (aka the German empire) were trying to exterminate anyone who followed the Jewish religion.
I don't see how anyone would not know that WW2 was about religion....unless they don't believe the holocaust actually happened
Umm no.You really need to get your WW2 facts checked.
Firstly, the reason Germany and its allies(don't forget that the axis also consisted of other countries) went to war wasn't to exterminate the Jewish religion, that's true even if you focus with Germany sans her allies.
Secondly, The criteria for the Nazi's extermination policies(racial/ethnic, political lines were stronger influence) weren't limited to the Jews,they're just the most "high profile" victims .There were also the Slavs , Romani and many other non Jewish victims.
And that's not even talking about the clusterfuck of mutual defence and alliance trigger that was World War One.
Religion is rarely a major factor in most wars.Even in religious wars like the Crusades both sides were busy fighting and backstabbing their brothers in Faith as much as the enemy.
