Only a subsection of White Americans are anti-Muslim: The Evangelical Christians. These group of people are messianic and have an obsession with Israel. The rest of White Americans are chill and mind their business without any obsession with Muslims. So by and large. White Americans are the least anti-Muslim group.
As for the French, Muslims, 6-million strong, are the largest minority group in their country. Muslim families tend to be having more kids than the French - who by far have only 1 or 2 kids or no kids at all. So with their declining birthrate, they worry about the growth of the French Muslims in their midst. Let us also remember France is where the Crusades against Muslims were initiated from during the Middle Ages.
For Britain, it is the seat and the birthplace of Freemasonry. All evil against Muslims and humanity are originated from that island. But they're clever than the French and their American compatriots. They tend to be less vocal about their hatred towards Muslims. But then you have to look at the problems that Muslims world-wide faced or currently face: You will definitely trace the root causes to UK. So I settle with non-Muslim White Brits being the most anti-Muslim, most evil people on earth. Just look at the UNSC and see which country is the pen-holder and constantly suffocating Somalia: UK.
