[4] In 2000, at the age of seven, Rochman experienced antisemitism after being physically removed from a bus in London, England, for being Jewish; he has described this experience as the origin for his will to defend Jews worldwide.
He is also known for his work as a Jewish and Israel rights activist on social media, where he has gained thousands of followers and subscribers across platforms and services such as Facebook, Instagram, YouTube, and Twitter.
During his studies at Columbia University in New York City, Rochman founded the school's chapter for Students Supporting Israel and served as its president.
[8] He currently serves on the board of The Israel Innovation Fund, a philanthropic organization, and as part of the leadership team of HaBayit, a platform that aims to bring unity through dialogue between Israelis and Palestinians.
[10] In July 2021, Rochman and two other Israeli filmmakers were arrested by Nigeria's secret police, the State Security Service, while filming the We Were Never Lost documentary.
His argument for the State of Israel's right to exist is not based on religion, but the point of view that Jews are indigenous to the land,[17] and that they have always yearned to return there since their expulsion by the Roman Empire.
Rochman has notably stated that, although "Jewish people's connection to a higher power and Torah is an essential part of their identity", Judaism is not a religion.
Rather, he refers to it as "a portable suitcase" that carries different elements of the Jewish identity, such as their culture, traditions, way of life and "a connection to a higher power".
[23][8][24] In December 2022, Rochman on a video posted to Instagram stated that "the majority of the Jewish people just walked into the gas chambers" during the Holocaust.
[25] Later that month, Rochman faced further criticism for defending basketball player Kyrie Irving, who posted a link on Twitter to the documentary Hebrews to Negroes: Wake Up Black America, which contains antisemitic tropes and Holocaust denial.
