Israel isn't foreign. That's the secret. It's like Puerto Rico to them but can feign independence and autonomy.
To hide this obvious truth they pretend to care about antisemitism, so they say hey don't criticize Israel, that's antisemitic. Because don't criticize Israel that's really our military asset in the region doesn't sell as well.
I would evaluate if you have reasonable beliefs here. Like do you have enough information to accurately describe someone as a sociopath? To claim what they "only care about"...?
In this case I doubt you do, so it's then strange to be so virulent and adamant.
