You seem to be mistaken in thinking I support Israel's treatment of the Palestinians. They aren't victims of genocide, but Israel is ghetto-izing the Palestinians in both Gaza Strip and the West Bank in a way that is morally reprehensible. However, it is also understandable that Israel and Egypt would seek to keep Hamas weak, given the history Israel has with Hamas and the history the current Egyptian government has with the Muslim Brotherhood. Since their tactics with Gaza are clearly working though, I won't condemn them. They have a right to defend themselves. And that may mean preventive measures when you're dealing with people who use suicide tactics frequently.
All of the Americans who think Israel's evil can say so because they're not the ones who have to deal with rocket attacks. If, say, the drug gangs in Mexico were to begin to lob nearly 200 rockets a day into Texas, Arizona, and New Mexico, I don't believe for a moment that Americans wouldn't be crying for blood. If this were a persistent problem for a couple of decades and the Mexican government didn't handle it, Americans would be calling for many of the same tactics the Israelis are using. So let's not be hasty in condemning the efforts of Israel's military and government to secure their population.
It is also clear that these protestors knew ahead of time what they were getting into, knew the history if the IDF with this blockade, and chose to do this anyway. They knew they'd likely get boarded, but they decided to go ahead with the plan and bring weaponry. Bad idea on their part.
Now, to jockboy, it is not a myth that Gazans are denied necessities. The Israeli government technically voted to allow medical necessities and food through, but the IDF has yet to actually follow that directive. There are some high-profile instances where an NGO makes some noise and Israel is shamed into letting some stuff through, but most of the time it's a full blockade. This was one of those instances where Israel offered to let the supplies through their checkpoint if the protestors would just turn back and hand over the goods. The protestors, obviously, refused.
