calling him 'crazy' or mentally unstable is a good way to be dismissive of his action and what drove him to do it. It also lacks a basic understanding of empathy...empathy into what may have driven him to take such an action...and the empathy that he may have felt for the people of Gaza.

this was his recorded statement he made on video as he walked to the embassy...I haven't seen this part of his speech mentioned in any of the mainstream media reports (for a reason).

"I am about to engage in an extreme act of protest but compared to what people have been experiencing in Palestine at the hands of their colonizers, it's not extreme at all. This is what our ruling class has decided will be normal."
