Apparently JP is on the defensive simply labeling anyone who makes a criticism of Israel as anti-Semitism. I don't know, it's the first time I've seen this in him.
I'm now guessing he might not, and they are Jewish people and not anonymous, however dubbed self-hating.
The context here is in not knowing what constitutes JP saying what he said - to who and for what comments, because some people can take it to extremes. Then again, many have tried to have civil discourse around issues that warrant criticism of Israel, justified criticism, only to be excoriated and tared and feathered. Thus if there is one thing pretty much everyone knows, you can't criticize Israel in the main and expect not to be taken to task.
So there is a chain of associations here, where the meaning of his life - and his struggle against nihilism and chaos - is tied to his love of the West and his Christian understanding, which is tied to Judaism as he understands it, which is tied to Israel's existence as the anchor of Judaism. All this might lead him towards a certain romanticization towards Israel, and to feel protective over it in the face of all of these massive global changes. Its common in times of chaos for people to turn to tradition. Maybe we got a glimpse of this in the video (linked above) of him imploring an Israeli audience with tears in his eyes that 'the world needs Jerusalem!' For him, at this point in his life, it may also be some sort of metaphysical anchor.
Yes, that could well be.
