He was my birthright advisor; his organization paid for a free* 10-day trip to Israel. I write free* because there are certain expectations when you return to the states, like preaching zionism. For those who aren't zionists, the trip is meant to "convert" your thinking. While my views didn't change, his organization spent several thousands of dollars on me. I feel guilty blocking him. Plus, it would cause big drama with the other students I went with.
