I have to ask, Whats offensive about that spray?

I am not trying to judge your ban or change your mind, But I just want to understand what I have missed about that spray? I may be missing something.

Thanks, Dave
I just find this spray depicting the concentration camps and human-sized furnaces to be racist as a whole as those things were used to show a hatred towards the Jewish race, I'm also not comfortable with this spray using Anne Frank as a joke and almost as a supporter when that was clearly not the case. If any other admin shows a different opinion towards this case, I'd appreciate if they shared it.
 
OMG...(slaps forehead)

I did not get it the first time. I see it clearly now! LOL
Thanks, Dave
