Do you think its time to really respond to the level of anti-Semitism and anti-Zionism this site has?

Everyday this site has dozens of questions showing the hatred that people have to Jews in this nation and around the world. Taking a similiar issue years ago a Black friend told me that even though I did not use the "N" word if I heard other friends or family using it and did not respond to it by stating its evilness I was just as guilty of using the word. Should we do the same on this site when we see ant-semitism
