The speaker highlights how anti-Semitism has existed throughout history, with varying levels of intensity and focus on different political spectrums. Currently, there is a concentration of anti-Semitism on the left in America and Europe. The speaker points out that some young individuals on the left, including homosexuals, feminists, and gender studies majors, show anti-Semitic behaviors by aligning themselves with radical Islamists who oppose the LGBT community and women's empowerment. Despite this contradiction, these individuals vehemently oppose Israel, leading to concerns that they may adopt extreme measures like wearing burkas to display anti-Semitic sentiments.
