American-Jewish actress and PhD holding neuroscientist Mayim Bialik - best known for her role in The Big Bang Theory comedy series - has long been an outspoken supporter of Israel.

She has repeatedly faced calls by anti-Israel activists to boycott her due to her views, and has told of the frequent hate mail she receives for her support of the Jewish state - particularly when, in 2014, she donated to the IDF at the height of Israel's Operation Protective Edge counterterrorism operation.

On Tuesday, she took to Facebook to make her views abundantly clear to the haters, posting the following

For those of you who refuse to follow me and discourage others from doing so because I am a Zionist (as if that's a crime!!), I highly recommend you look up Zionism in a dictionary rather than using the definition perpetrated by anti-semitic media and leaders. Zionism is the belief that Jewish people deserve an autonomous homeland free from terrorism and threat to our global existence. if you don't want to follow me because I believe in that, by all means don't.
