I think you should do some research. The allegations of a massacre and rapes at Deir Yassin have been debunked by testimony from Arab villagers who were there as well as by Jewish militia participants. The village was not a peaceful unarmed village. When it was attacked in a war started by the Arabs, it was a legitimate military target. Shots were fired by both sides.

It was quickly and widely publicized as a massacre by Arab media, who embellished it with more and more fabricated details. Jewish sources who came by later saw a war-torn village and burnt bodies. But none of those sources were actually there. This book that takes testimony from sources who were actually there. It finds a concurrence from Arab and Jewish primary sources: civilian killed in the battle — yes. a massacre and rapes — no.
