Why can't an honest civil answer about Israel gets deleted?

One time I answered a question about why aren't there Jews in Arab nations, and I named countries such as Syria, Iraq, Iran, Morocco and Turkey with a long standing history of a Jewish population. The person who asked me gave me best answer and 5 starts. Yahoo deleted it, reason, violation of terms of service. Someone asked another question about traveling to Israel and purchasing land, I said it was Ironic that Palestinians in Gaza will never see the light of day in Jerusalem.....deleted why? violation of terms of service. Is Yahoo owned by Benjamin Netanyahu or something. What happened to free speech here? I hear a lot of racist comments about Obama in Yahoo and it never gets deleted. I see anti- Arab and anti- Islamic hate - all the time. Why in America any discussion about Israel is off limits even for debating purposes? Even the Israelis don't have this problem - their newspapers tell it all, even when it seems to go against their own policies,but in American it is taboo to say anything even slightly against the policies in Israel, for instance in Gaza. Why are Americans labels anti semite for everything for the slightest of comments? What made them above approach. (no religious babble about them being the chosen ones.) The Jewish race has surely produced brilliant scientist and thinkers, but they are not alone.
