I might have agreed with you about coming to America to study, if you had mentioned the repression-type issues we have here, whichever side you’re on, for example, families being separated at the border or African American males being killed by police.

Israel has problems, the US has problems, but so do a lot of other countries in our world. And then there’s South Amercia and Africa. Again, the student can choose to study wherever they want to, the LOR should be about the student not the teacher
