Does criticizing (mildly or strongly) the Israeli government make you anti-israel?
If being anti-Israel is anti-semitic does that make Satmar anti-semitic?
There's a known story by the Satmar Rabbi zatzal. (Rabbi joel)
One of the politicians came to him for a "Bracha" and endorsement (I forget who it was) and he was warned that he shouldn't tell the rabbi that he's a supporter of israel, as not to loose the rabbi's support.
He failed and he told the rabbi that he's a strong israeli supporter and the rabbi endorsed him.
When he left the "gabbaim" asked the rabbi how come he supports someone who supports zionism?
The rabbi then tought us a strong and important lesson.
By a non jew loving jews materializes itself in loving israel if he doesn't love israel he's likely a anti semite.
