I also do not believe the effectiveness of the flotillas will be in their quantity of delivered aid or successful landings, however I see the value of raising the Red Cross/Crescent and sailing towards a war zone with the declared intent and cargo in preparation to disperse aid to force the idf to stop you.
That action (and it is action) makes clear to any observer that the intent of the zionists is genocide.
I’m not familiar with the person you’re posting about but military detention by the idf is not the same as being arrested and I’m not sure what you can possibly be trying to accomplish rhetorically by equating the two.
