Granted, your point is valid, but that’s NOT the issue here.
The issue is that, right in the article itself, the professor states that he would “gladly provide her a letter for any other college that is NOT in Israel.”
THAT is the issue, NOT any sense of entitlement on the student’s part. Were I in the same situation, my response to the professor in question would be: “You know what? I’m good. With an attitude like yours, I’d just as soon NOT have someone like you on my CV.”
THAT is what I see as the main issue here.
Agreed, having the professors opposition to Israel in the public record is a good thing, which it now is. Students can make choices based on knowledge of his leanings, the institution can make choices on what kinds of messages they want to send to prospective students.

The millennials are way too media savvy for that. They've learned that becoming a public cause celebre and a victim is a much faster route to success.
