It is not only famous people in the UK who have given unusual names to their children...many aristocratic, middle-class and working-class people have given unusual names throughout the ages. This is especially true since the 1960s when psychedelia had quite an influence on popular culture. A surprising number of people have changed their names to seem less pretentious.
Shakespeare did not only sign his name with a flourish, he used variants of his name, a fact which is universally acknowledged. Many medieval and renaissance people did the same, here and abroad.
I have worked extensively in American studies, specialising in slavery, and also on diaspora issues, and I can assure you that names are of paramount importance...I have attended name-changing ceremonies for older people who wish to rid themselves of western influence, and also travelled throughout the Caribbean where in some places the same issues of birthname and birthright are always forefront in the people's awareness. Basically you are saying that a 17 year old Black American is too stupid to understand such issues, and that is what I find intirinsically disrespectful in your post. You speak of certain groups as 'they' without even indicating which ones you are speaking about...poor Blacks lumped together with chavs, etc etc and snobbishness pervading throughout. Why don't you do some research (even for simple subjects such as Shakespeare's name) before wasting space? I have been fed up with AB for ages but this is the final piece of stupidity and I am not coming on here EVER again, and that's FACT
