If Israel was so "disproportionate", why was there only violence on one boat?

I have asked a simple question.

And I bet that all of Israel's enemies will be unable to answer it.Their hatred has destroyed their rationality. They are no longer able to engage in any sort of logical discourse. It is highly reminiscent of the Nazis attitude towards the Jews.

The truth is that on one boat the Israelis had to deal with "Insani Yardim Vakfi" (ihh). As you can see from the above link, it is an extreme Islamist "charity" with links to terrorist organizations.

One of the Naval Special Forces commandoes who sustained a broken arm while under attack by the Mavi Marama ship’s passengers, reports, “Each soldier who descended was taken by three or four men and they simply exploded, beating him up. They lynched us.

“They had metal clubs, knives, slingshots, glass bottles…At one point there was also live fire.
“I was among the last to descend, and I saw that the group was dispersed, everyone in his own corner surrounded by three or four men. I saw a soldier on the floor with two men beating him. I peeled them off of him and they came at me and began beating me with the clubs.
“That’s how I broke my arm. At that moment I had no weapon in my hands, like everyone else who descended on the cables empty-handed. My paintball gun was behind me.
“They came and attacked me, I brought them down to the floor, I took a few steps back, I took out my paintball gun, they came at me, and I shot at their legs. One of the clubs destroyed my paint gun and I moved on to my pistol which was the only thing to hold against them. At this point my arm no longer functioned.
“From the opening of the corridor, they were shooting at us the entire time with live fire”
The naval soldier also described how his unit was shot at from the entrance to the ship’s corridor: “I saw two from my group lying flat on the ground. From the opening of the corridor they were shooting at them the entire time with live fire, bullets. We identified a gun barrel, and one of us shot at the guy holding it. Afterwards we entered and he wasn’t there.
"[They were] about 30 men; they simply came for war. We came to straighten things out, to speak to those who went downstairs, but each of us who descended was simply attacked.
“There were some from my group that were thrown to the lower floor, and the passengers took their equipment. They jumped to the water as a last resort. We were told that if they didn’t listen, we should shoot at their legs with the paintball gun. 'The pistol is only for if you really feel your life is in danger, which shouldn’t happen. It would be extremely abnormal.' But in the end, that is what happened.
“We came with the intention of stopping the ship and taking it to Ashdod, and we did not come with the weapons we usually have; we came for something entirely different.”
