"the source you gave is not reliable and in addition its an israeli who wrote that article".
Israelis are just as capable of writing objective information as Palestinians are. In fact, if you read carefully you will note that the research was conducted by a Palestinian group.
"Please do not change topics: we are not talking about Osama bin Laden, but the suicide bombings in Israel."
Terrorism in one country is related to terrorism anywhere. They share many of the same causes.
"Of course there are Palestinians who support the suicide bombers, but that figure is no where near 70%, maybe more like 10%."
This is a hilariously low figure, with no basis in fact or common sense. Whenever a hamas terrorist is executed by israel, massive crowds of 30,000 and 40,000 terrorism-supporters come out to show their support.
"I have a few friends who have relatives there and when I asked them, they condemned it, want peace and get rid of the terror wherever it exists in that region."
Your friends are in the minority.
"Well, I will not look into this post anymore and I wish you a nice day!"
Of course not. You want to preserve your deeply-held belief that regular Muslims do not commit terrorism, so you will go out of your way to avoid any evidence to the contrary. That includes intentionally avoiding posts that threaten your beliefs.
