Antisemitism means being mean or harmful to Jewish people, just because they are Jewish. In Italy today, some people still hold hateful ideas and beliefs towards Jewish people, even though it is wrong and against the law.
This kind of thinking is not good because it can make Jewish people feel scared, uncomfortable, and unsafe. It can also lead to discrimination, where they are not treated fairly in things like jobs, housing, or social situations.
There are different reasons why some Italians might feel this way towards Jewish people. Some people might not like them because they are different from them, in terms of religion or culture. Or they might have heard harmful rumors or myths about Jewish people, which are not true.
But it is important to remember that everyone is equal and deserves respect, no matter what their religion or background is. It is also important to speak out against antisemitism and work towards creating a society that is more tolerant and accepting of diversity.
