Is this english thing about a royal wedding a coverup?

People in my county have been going mad over the "supposed royal wedding" which i say frankly is to suspicious. William is a strapping young lad with a great background and yeah that bird is beauts but ive heard shes not of divine blood, it doesnt sit well in my stomach. If you also noticed her sister and her look IDENTICAL the spit of each other. Me and my gals feel its obvious there going to send kate to another country to publicise the self concious britian while they hide this from the people and pretend her sister is her but why cant love be enough to marry anymore?
