They were still way over the line and he apologized. But I did not see any of the claims of "openly calling for genocide in Gaza". Did you? You may link some quotes then. Possible I missed them, but I rather think, this was the usual hyperbole.
"innocent civilians" was the only questionable phrase, but still not at all a clear demand to kill civilians, rather a doubt whether armed civilians, who want to kill jews, should count as civilians.
Can you share a quote here, that you think was a open call for genocide in Gaza? Then we can debate concretely that and not something meta.
