Your question is, indeed, an interesting and somewhat troubling one, nomdeplume.
I believe that, yes, male curls in the arts have had a significant effect on Western culture. In perusing the collected works of Shakepeare conveniently situated on my bed, I have noticed that the common denominator between most actors pictured on its pages would seem to be curly hair. Can this be coincidence? Given this startling trend, it would seem to me that some of the great works of the theater were written specifically for the curly-haired male. Without him at the basis of our dramatic structures, we would in all likelihood not be able to enjoy the theatrical experiences that link us all together in this little corner of cyberspace, and therefore the curly-haired male's cultural influence is by no means insignificant.
The lack of curly hair in many historical figures is somewhat troubling. Take Napoleon as an example. His obviously unnatural attempts to create curls point to a deep-seated psychological trouble, and is at the root of his destructive path. Another obvious example would be Mussolini, whose curl bereavement very likely began his obsessive grasps for power.
Therefore, while the perfectly spiraled male coif has been a beneficent influence on our society, we must be very careful in allowing such a trend to continue. It would be shocking, indeed, in our supposedly broad-minded society, to allow the continuation of discrimination against the straight-haired, as we have seen the horrors this can lead to. We must strive for a society, at least within the theater, where the curly and straight-haired can work together, for the betterment of all.
