How was Hitler such a cool dude? Well he did get 6 million people baked for the rest of their lives.
I would refrain from making jokes about the Holocaust. Don't you feel like this is nonsensical?
It's not bullshit, it's the truth.
I think it's important to know that making these type of jokes about Hitler and the Holocaust can offend a lot of people. Try to put yourself in their shoes, think of how it would upset them having to relive those atrocities. I think would be great for you to educate yourself on these atrocities so it would change your mindset on this.
