This statement is not meant to be racist in any way, shape or form, and should not be taken that way. Just an honest observation:
Many black males have an extremely similar "fade" style haircut. Some have a flat top and shaved sides, and some look like the "bowl cut" done with clippers. Many have an artificial part made with a razor.
You cannot tell me that this little boy's high and tight is that different from the short clipper haircuts that many black males wear and that is never questioned by anyone as distracting or controversial.
If I was that child's parent, before I gave in to that principal and humiliated my son by having his head shaved, I would have my attorney carefully scrutinize the haircuts of every other child in that school (and entire school district for that matter),
and if any other kid had a similar haircut, and was not asked to shave their head, there would be hell to pay.
