Do their constituents happen to be Muslims?
You better believe it. Sorry to say, but the Monarchy will die when Elizabeth does. Ol Chuck will hand the country over to the Muslims the day she’s laid to rest
Bingo! You've revealed the real reason behind this challenge. Muslims do not want to swear allegiance to queen and country. They only swear allegiance to Islam, it's rock god "Allah", and it's disgusting little pedophile prophet, Mohammad, the mass murdering bandit and thief, and swear to follow in his footsteps waging war against all mankind advancing "Allah's" cause, no matter how bloody.
Ishaq:204 "Men, do you know what you are pledging yourselves to in swearing allegiance to this man?' 'Yes. In swearing allegiance to him we are pledging to wage war against all mankind."
Ishaq:471 "We are steadfast trusting Him. We have a Prophet by whom we will conquer all men."
Ishaq:208"... Now we bind ourselves to war against all mankind for Allah and His Apostle. He promised us a reward in Paradise for faithful service. We pledged ourselves to war in complete obedience to Muhammad no matter how evil the circumstances."
Qur'an:8:7 "Allah wished to confirm the truth by His words: 'Wipe the infidels out to the last.'"
But islam is a religion of peace, dontchaknow...
