I wrote to the Guardian’s editors, including Gibson, sharing with them a blog post I published expressing outrage that they would hire a columnist who “who openly called on the Israeli army to kill Americans”.

I also asked the editors if they had been aware of [Joshua] Treviño’s violent statements - and whether publicly calling for the killing of those whose positions you disagree with is merely another opinion we are bound to respect and tolerate.

The response was disappointing. “We have long held that a range of voices is one of the great assets of The Guardian’s comment section” the company’s press office said in an emailed statement. “We look forward to the open and robust debate that we are sure will follow between Josh and Guardian readers,” the statement added.

The press office also sent me the link to a piece Treviño wrote - no doubt at the urging of his new bosses - to counter the growing outrage over his calls to kill flotilla passengers.
