In my experience something similar exists with a subset of Russians, - they hate Israel the particular way, they just love the fact that it exists and commits crimes.
When you are Jewish and proud of yourself, it makes them just as livid as when you are Armenian and proud of yourself.
Republic of Armenia is quite miserable and they enjoy that, Israel is strong, but lacks dignity even more than RoA and they enjoy that, so the emotion gets especially extreme when you put these states and your own pride and the fact that they can change and have dignity in contrast.
