Northern Ireland’s Health Minister Robin Swann wrote a scathing opinion piece for Rolling Stone magazine on Sir Van Morrison.
Last week, the singer announced three new songs protesting the coronavirus lockdown.
In the lyrics, he claims that scientists are “making up twisted facts” to justify measures that “enslave” the population.
Mr Swann said the songs were “dangerous”, challenging Sir Van to present his own scientific facts.
The minister echoed these thoughts and elaborated on them in a highly critical article for Rolling Stone magazine.
The monthly American title focuses on popular culture, including music, entertainment, and politics.
Describing the track, the editors of Rolling Stone said: “Swann oscillates between disappointment, bewilderment and anger at the new cause of one of Northern Ireland’s most famous singers. “
In the article, Mr Swann criticized Sir Van and the potential damage he could cause to public health messages around Covid-19 in Northern Ireland.
He wrote: “We in Northern Ireland are very proud of the fact that one of the greatest music legends of the past 50 years has come from our part of the world.
“So there is a real sense of disappointment – we expected better from him.
“If you see it all as a big conspiracy, then you are less likely to follow essential public health advice that protects you and others.
He added that governments around the world are “struggling” to find their way through the pandemic and that it is “just and appropriate” to debate and question policies.
“But Van Morrison goes way beyond asking questions,” he said.
“He sings about ‘fascist bullies’ and claims that governments are deceiving people and want to ‘enslave’. ”
Mr Swann said the songs were a “slander” on those involved in the public health response to the virus.
“His words will give great solace to conspiracy theorists – the aluminum hat brigade who cross over against masks and vaccines and think this is all a huge global conspiracy to suppress freedoms. ”
He added: “Everything is weird and irresponsible.
“I just hope no one takes it seriously. He is neither a guru nor a teacher. “
