How can I stop my mom from teaching my little sister anti-semetism?

[Mimi-BUSY]

My sister is now two months and ten days old and whenever she cries, my mom starts to swear at the Jews. I feel so angry when I hear that but I can not do or say anthing. She is my mom and she is already angry at me because of my political views towards Israel which she considers evil.
All I want is peace. I don't hate the Jews at all and I have Jewish friends. I don't want to hate them and I also don't want my siblings to hate them. But if my mother keeps doing that, my little sister will grow up as an anti-semite. My mom is like a dictator and she refuses to listen to me whatever I say or do.
My father is understanding but he often says anti-semetic things like her.
Please help.
I was anti-semite for 20 years. I only started to like the Jewish people two years ago and I made Jewish friends. I don't want my siblings to be anti-semites at all. What my mother is teaching them is wrong and I only realized that at an "old" age.
Gloria, I met Jewish people and I found that they are so nice and cool. I also don't like it when someone swears or speaks badly at another and I noticed that most muslims like to speak badly of the Jews. I studied about Judaism and I found that it is very very similar to Islam and I think we and the Jews have a lot of things in common, so why should I hate them. I try to seperate politics from religion as much as I can. Even when it comes to politics and I am Palestinian, I tend to tolerate some of what the Israelis do, because Hamas are evil fanatics.
