I didn't insult you, don't insult me.

How isn't it? America was founded on the literal genocide of Native Americas, but you don't consider that an Illegitimate nation. UK had all sorts of wars over the years massacring many, many people. But you don't consider that an illegitimate nation. Australia was founded by the genocide of the Aborigines, but you don't consider that an illegitimate nation. Not even getting into places in the Middle East where democracies have been overthrown for dictators or all the suffering in the African continent.

The difference is one country is Jewish, the others aren't.

So you calling the Jewish one, but no other, illegitimate is pure Anti-Semitism.
