First of all, it's not a good look ending an anecdote about a terrorist attack with hahahaha's.
Second, Spain ain't funding Hamas or Isis (which you for some reason bring up.)
Third, we're not rooting for one side or the other to conquer the other. Most people believe arming people who murder civilians is a bad idea.
Fourth, Israel is clearly murdering civilians and engaging in a plethora of war crimes. It's not odd that Spain doesn't want to be complicit. That shouldn't be difficult to grasp no matter if you root for one side, the other or just hoping for a peaceful end to this conflict
