Like I said.A lot of it stems from hatred due to israel bombing of innocent civilians, hospitals (which is a war crime), and children. And especially since israel's occupation is illegal. You can't build settlements on occupied land. If I'm not mistaken that is illegal by international laws. And I think building barriers also conflicts with international laws.
Edit: Compare israel's attacks vs hamas attacks. Israel has an app to warn people of possible bombings. While Palestinians have nothing. Not only that but you remember that funding we were talking about? Israel has far better weapons than hamas. Yet they deliberately fire in densely populated areas as well.
So immersed in a culture that they will have to be forcibly removed from that culture in order to understand that another perspective is valid.
You do realize that there is no such thing as 'international law.' You also realize that the arabs in Gaza have no legitimate claim to the land. They are not descendants of the philistines - that group of people has been gone for a very long time.
Israel can do what it wants on its land. If they want to build a wall - they can build a wall (perhaps the arabs could stop blowing things up, and then there wouldn't be a need for a wall). If they want to build settlements - they can build settlements. We have a concept known as imminent domain in America that prevents the government from just doing whatever the hell it wants without fair market value compensation for forfeited property - but the not-palestinians have routinely refused to sit at the table and discuss the concept of property ownership and property rights within the nation of Israel.
IE - If the not-palestinians were to simply accept their place within Israel and have it worked out so that they could own property - then there wouldn't be an issue.
As for the bombings - Israel uses small (and expensive) charges that are dropped on the roof of a building prior to the delivery of primary ordnance. These small charges are meant specifically to clear people out of the house so that they are not reduced to partial remains.
This is necessitated because the not-palestinians are known to keep their wives, children, friends, and passers-by cooped up in houses that they know Israel is likely to bomb (this is also why they store rockets in U.N. provided schools and launch said rockets from the roof of hospitals, the playgrounds of schools, etc) - specifically so they can claim civilian casualties and brutality.
Frankly, that's more trouble than it's worth. I'd drive them all into the sea and be done with it.
