Jewish actress Mayim Bialik took to Facebook on Tuesday to condemn those boycotting her on social media due to her pro-Israel beliefs.

“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,” Bialik, who is also a neuroscientist, wrote.

The “Big Bang Theory“ star said Zionism is defined as the belief that Jews deserve an “autonomous homeland” free of terrorism and threats to their global existence. “If you don’t want to follow me because I believe in that, by all means don’t,” she announced.

Facebook fans lauded the actress for speaking out in support of Israel and remaining true to her beliefs. One user encouraged the 39-year-old mother-of-two to “stay strong,” while many others might “crumble under the pressure to conform to society.”

Another said: “Thank you, Mayim, for speaking out for all of us Jewish people who don’t have a voice that can reach as many people as you can. Thank you for being such a great supporter of all the Jews worldwide.”
