Yes, it is. He should have stated defense of murderers.
But, is it more offensive to you because he is calling the Jews murderers?
If he has stated that to me about Palestinians you probably would have agreed.
Anyway, there is no dispassionate debate on this, I can admit the atrocities of Hamas and terrorists, having said that the other side, IDF, always gets a free pass from some as though every action is justified.
A completely tragic situation now with children and women starving, this never had to happen and both sides share in the corruption equally, along with British settler colonialism the start of the problem.
