Ok but how about answering my questions.
Your question isn't answerable.
The flow of conversation was "Hamas wants to kill Jews". PG said, "prove it." Then you switched the conversation.
Palestinian leadership has been speaking about killing Jews since the beginning of Palestinian leadership, and Arab leaders were doing so before then. That's what incites the population to kill Jews, and it is what incited them to kill Jews before Israel was formed.
This is born of consistent hate messaging by leaders. Who is to say what percentage of the population would do that? There is no way to know that that very individual would have predicted himself lynching a Jew the day before he joined a mob and did it.
