One letter writer to the Daily Telegraph argued: "The trouble… is that almost every person of that era held opinions that were commonplace at the time but are at odds with modern thinking. Taken to its extreme, this approach would lead to the eradication of almost every building and statue commemorating notable figures of the past, including the Albert Memorial and Nelson's Column."

The university’s chancellor, Chris Patten, told students that if they could not embrace freedom of thought, they may “think about being educated elsewhere”.
In an article for the Times Literary Supplement, the celebrated classicist Mary Beard told the students: “The battle isn’t won by taking the statue away and pretending those people didn’t exist. It’s won by empowering those students to look up at Rhodes and friends with a cheery and self-confident sense of unbatterability.”
