The Hebrews (Jews) are semitic and I do not know of anyone who claims the Jews are a distinct race. Modern day Jews are either those who can claim direct descent from one of the sons of Israel (Jacob) and have maintained their identity as the sons of Israel or have converted to Judaism.
The site you linked to supports the heretical teachings of one William Barnham who just happens to believe in and teach Replacement Theology as well as what is known as Kingdom Theology. He is also supported and acclaimed by the name it and claim it groups that have deceived millions. In other words the site you linked to is antisemitic to the core.
Also the word "Jew" in the Bible should actually be "Judean" and if you have actually studied the prophesies concerning God's chosen people, God promised to reunite the split kingdoms of Judah and Israel and return the Promised Land to His chosen people when Jesus Christ returns to rule for 1,000.
You can choose accept and believe antisemitic propaganda, but I choose to believe God.
