Unrelated to this article and reeks of antisemitic tropes.
That being said I don't agree with OP.
Yes, it smells like antisemitism.
If someone made an off topic comment about China or Obama or whatever, I'd suspect their motivations on those too.
It doesn't mean that every criticism of Obama or China is necessarily racist, but boy is it hard to read goodwill in comments where that sort of thing is irrelevant.
