Batya Wootten and Marshall Koniukowsky. What error do you think they teach? I know nothing of these people.
There are a package of assumptions and beliefs that all go together, mostly revolving around the (mis-)understanding of the national and political history of Israel during 722BCE to 100CE.
1. A key part of the propaganda is telling audiences of random Gentiles that, "You
could be Ephraimite!" While the bald words seem fair and reasonable, one must view some of the videos to see how quickly "could be" turns into "you
are" in the course of an hour seminar.
2. Having told the audience that they are Ephraim, the usual tack is to then displace modern Jews, marginalizing them by alleging that they are "only 1/12 of the Israeli nation". This seems reasonable to people who are not familiar with the history of the captivity and the restoration of Judah after the return from Babylonia.
The net effect of this "push-me-pull-you" approach is to slide in a Replacement Theology world view, where Jews no longer count as flag-bearers of Jewish identity, and are replaced by a bunch of Gentile Jewish-wannabees calling themselves "Ephraim". If you review Jim Staley's popular youtube video entitled "Identity Crisis" (a video frequently circulated by newly enamored Hebrew Roots disciples), you will see this exact process played out.
Hebrew Roots people tend to marginalize actual Jews and Judaism, and come on like gang-busters, telling the Jews "how it should really be done". They bring with them a rabid form of Protestant Christianity and a great deal of ignorance regarding the development of the Jewish people and Jewish theology. Thus, they say things that sound positive, like, "Just show me from the Scriptures...", while completely disregarding the rabbinic discussion and the development of Jewish practice and belief prior to the time of Yeshua.
Hebrew Roots should be viewed according to the original title--"Hebrew Roots of the Christian Faith". It is a Gentile movement designed to displace modern Jews and replace them with Gentiles who think they are justified in claiming a bloodline they have never documented.
This is different from a Christian who crosses paths with HR teaching on his way from the church to the synagogue. One is a necessary part of a learning process on the way to Messianic Judaism. The HR position stalls out, telling people to reject both Christianity and Judaism.
That made me laugh so hard Sprite shot out my nose all over the keyboard! 
Don't want to insult your intelligence.
