One would likely be more concerned with being accused of "anti-semitism" and having your name google-bombed by a Zionist smear campaign like Canary Mission.  Imagine having a potential client or employer finding your name on a list of "anti-semite Israel haters" for doing nothing more that suggesting Palestinians have human rights or that Israel engages in an aggressive espionage campaign against the United States?
Now if it would be an Iranian spy for example, they would hunt him/them down with the full force.

1 was spying on Israel for the US and was arrested and convicted by Israel.
China has been doing this too. Any time someone brings up Chinese civil rights abuses, there's always one or two people crying racism, even though the victims are (mostly) also Chinese.
