I criticise Israel all the time without being antisemitic.
But your post holds Israel to a double-standard, which is antisemitic. "Children are being murdered" says this is intentional on Israel's part, rather than a horrific side-effect of an unprecidented urban-warfare environment.
A non-antisemitic way to make the same point could be "the tragic loss of life, especially of children, confuses people as to what is right or wrong, and who's responsible."
