Yes, it is important for Christian parents to teach the whole counsel of God as found in the New Testament.
An important part of the Gospel is that Jews killed Jesus Christ.
This is emphasized in the Holy Bible, because God wants every Christian parent to teach their child this fact and to treasure this Gospel Truth.
The Bible is the Word of God!
Jews are proud to be Jewish. Judaism is a false religion. Jews rejected and killed Jesus Christ.
It is a shame that Christian parents are not proud of the Christian Gospel enough to raise their children to be anti-Semitic, just like Jesus Christ and St. Paul.
This explains why America’s Christianity is such a mess! Christians in the United States of America are ashamed to be Christians! How do you think God feels about that?
Anti-Semitism is a very important heritage of Biblical Christianity and every Bible-believing Christian church must embrace anti-Semitism as an important part of the Christian Gospel itself!
