Neither is "only being part-Jewish." We Messianic Jews are just as "Jewish" as non-Messianic Jews. The difference is that we aren't bound by Rabbinical oral law, we are bound by God's law ONLY.
I stand beside my brother's DSM and So Jewcy, who are both Messianic Jews. And I reach across to Suckels the Clown of Righteousness, who is grafted into Israel and is also my brother.
Those who wish to demean us and launch personal attacks, are merely jealous of the joy we have found in Messiah Yeshua. One day, they will know Him and bow to Him.
Shalom,
