I didn't think that would happen in Armenia, but since it does - the way some Armenians act towards refugees from Artsakh is similar, I think.
It's easier for Israelis (especially when being fascists) to think that they themselves are strong, and those survivors are not like them, they are weak. It's as they wanted to identify with Nazis more.
With such Armenians too - it's the worse part of them thinking they can be just like Turks if they suck up to Turks, and also because Artsakhtsis lost their homeland for being weak, and they are not weak.
A bit like ignorant and cowardly people abandon relatives with chronic diseases, when there's no evidence of those diseases being transferable.
It's just cowardice. Humans do it under pressure or when presented with dark events for their interpretation and self-identification. While good upbringing may reduce the risk of someone growing up a coward, it's very human.
