That video was actually received very positively as a joke on a lot of Israeli forums.
This is more of a sign that most people who get offended get offended for the sake of others rather than themselves.
For one, there are a lot of Jews outside of Israel.
Apart from that, I am offended not just because it's disrespectful towards a particular minority. I'm offended because this is a thoughtless comment which "jokingly" parrots hostility towards other people at a time when I'm already worried about how that kind of message is being spread in earnest by a large number of people.
Go to any left wing rally and you'll see much worse than "hitler did nothing wrong" memes.
This, in my experience, is how every right wing rally is. Left wing rallies, on the other hand, have always been very pleasant and highly enjoyable.
Thank you for your perspective.
