Messianic Jews are viewed as traitors to their own religion and treated as such.
Kinda like a Christian from your own personal church converting to Islam and then constantly coming to your own Sunday services trying to convert everyone to Islam. And when it goes on and on and on for decades (different peoples at different times), you eventually get fed up with it and try to drive them off.
“Messianic Jews are viewed as traitors to their own religion and treated as such.”
Unless they are acting as a travel agency for Israel.
