There is a difference between nazi propaganda and making fun of Hitler.
So in my eyes it's not offensive, unless you are a nazi.
Oh, those hitler videos are fucking hilarious IMO, but Holocaustard is pretty uncool. Doesn't seem like a good marketing decision. I'm not gonna cry about it, though. Don't really care that much, I just wouldn't give them my business.
I'm not religious at all, quite the opposite actually, but I was raised Jewish, as my family is. I won't deny that could definitely influence my feelings on the juice name. Again, I'm not offended by the hitler videos at all, quite the opposite.
