Naw, not 'offensive' at all;

just a bit revealing of the truth, which some people don't want to deal with.
She and other family members say the student should not have been sent home.

“His story’s got to come out,” Harris said only moments after putting the teenager on the airplane. “There should have been a better way to handle this.”

The 15-year-old student is accused of writing “Death to Americans” in Arabic on a classroom board during a discussion with classmates.

Harris said the teenager wrote the words on the board when interacting with another foreign exchange student an American student during a class at the school.

The student’s father, Khaled Kasab Mahameed, said the phrase was not written as a threat or with any malicious intent.
Really? Generally, I'd having trouble believing that; then we get down near the end:
Mahameed’s son was studying at Niceville High as part of the Youth Exchange and Study Program (YES) through AYUSA Global Youth Exchange. YES was created in 2003 through a grant to AYUSA from the United Stated Department of State to “build bridges of understanding between the United States and countries with significant Muslim populations,” according to its website.

Mahameed said the message of understanding between cultures is one that his son has advocated, no matter how difficult for himself, since he was about nine years old. The teenager’s family members are Muslim Arab Palestinians forced, Mahameed said, to leave their homeland a generation ago. They now travel and teach other Muslims and Arabs about the Jews as they advocate a message of peace.
And with that the little red flags and warning whistles all went off.
'Forced' to leave their homeland? Teach other M and A 'about the Jews'?
Gee, why do I find it more difficult to believe, after reading this, that 'Death to Americans' didn't actually mean anything? Either there's a lot of the incident we don't know, or the bastards ought to all be thrown out of this country.
