The "harmless" persons at the previous boat were not so harmless. They harm Israel when they support those who hate it. They harm Israel when they talk about the situation of Gaza as if it was Israel's responsibility when it's truly Hamas responsibility. They should claim for the end of Hamas so they would not need to claim for the end of the siege because it would be consequently ended. Not to mention that they seem not to care about the constant attacks Israel suffer from Gaza. It may not be hate, but it's certainly not love for Israel.
