Israel is just taking pre-emptive action to stop people pointing out that its policy of settlerisation and ghettoisation of Palestinian land is pretty much the same as the Lebensraum policy of Germany in the 1930s. If they really objected to being called those names, or have protesters wearing those symbols, they'd stop their own behaviour that led to it. If holocaust survivors find it disrespectful, then tough. Stop behaving like their old oppressors then.
