"Here's some video that was smuggled from the Rachel Corrie, in which we can see and hear the guy speaking for the ship tell the Israelis that the Rachel Corrie would be willing to be inspected by a neutral party like the UN."

So you ignore the FACT it was the M Marmara that had violence- and bring up the ship where none occurred.

Not exactly "proof that it's not weapons that the Israelis were concerned about."

The prohibited items of the embargo are those items that can be used for terrorist activities- such as the manufacture of those homemade rockets YOU say were not supplied by Iran, and explosives ( gelitin, margerine, etc are used as base materials for some explosives)
