How do we as Muslims respond to France’s attacks on the Prophet Muhammad pbuh?

So we shift to France this morning, where comments made by French President Emmanuel Macron in the aftermath of the beheading of a local schoolteacher have caused a furore in many parts of the Muslim world. As we know, this teacher had apparently shown his pupils cartoons of the Prophet (SAW) as part of a class on free speech. Macron has vigorously defended the publication of the cartoons depicting on the grounds of freedom of expression. The Islamophobic remarks have led to calls for boycotting French brands, and hashtags such as #BoycottFrenchProducts, #MacronApologizeToMuslims and #NeverTheProphet have been trending on social media.
Why is Macron wrong on the freedom of expression debate? And how should we as muslims respond to this contentious issue?
Well to help us make sense it all is Prof Muhammad Haroun, an academic in the Theology and Religious Studies Department at the University of Botswana
