Professor Christine McNulty has excelled herself with her outlandish opinions this time (Revealing differences, Letters, April 3).

To argue that the USA is a model in tackling the spread of Covid-19 and that the NHS is failing because of ‘…bureaucratic regulation’, beggars belief. As with so much of Christine McNulty’s utterings she doesn’t let the facts get in the way of her arguments.

The USA has a mainly private health sector whereas in the UK we have a health service. Despite the USA spending twice the amount on healthcare per head as the UK, at 16 per cent of GDP, the USA has millions of people without any healthcare provision and has 50 states having to struggle with Covid-19 separately. Hence New York is on its knees with inadequate help from the Federal Government and with a President who is in denial of the reality of the plague affecting his nation.

Thank goodness for our NHS, with its dedicated professionals and its values of providing high quality healthcare rather than making money.

Despite Christine McNulty’s views, I would defend her right to express her political opinions, whether it be on food regulation, the ‘nanny state’ or Brexit as in recent correspondence.

However, I do not believe she has the right to deny scientific facts and propagate climate change denial. It is now an incontrovertible truth that the planet is facing a climate emergency as a result of human-made global warming. There are legitimate political opinions on how we tackle this but it is not an opinion or a scientific debate as to whether it exists. The climate emergency is a threat to human life just as racism and eugenics are to people of colour. Neither should be given a platform.

Secondly, If Christine McNulty is to be allowed to prefix her name with the word Professor, then this should be validated. As the late Anthony Bramley-Harker pointed out last October on your letters page, McNulty is not registered with any academic institution as a Professor. She is using this prefix to give weight to her opinions and arguments. If she is genuinely a professor let her state her academic status and specialism.
