German in the Knesset?

Since we clearly are mentioning the War, here's another one. The German press has begun to pick up on an Israeli disagreement over whether the German president should use the German language when he speaks from the podium of the Knesset next month. The protesters want to ask him to speak in English.
I understand that the language may provoke difficult feelings in individuals. But especially considering we've already had one German president speak to the Knesset in German, with little reaction from survivors, this hysteria seems to be an easy -- but diplomatically offensive and dangerous -- attempt to score points on the part of a bunch of MKs who are not themselves even survivors or descendents of Holocaust victims.
The president of Germany is a symbol and figurehead for Germany today, including, rather centrally, its German language. As a state, once you have invited the president into your parliament, you have potentially invited the German language in as well. If, sixty years on, you're not ready to accept the latter, you're not ready to invite the former. Simple as that.
