Regarding the previous entry, I sincerely apologize for inappropriately classifying one of my fellow student. I have no personal interaction or personal conflict with this particular student. I have no reason to make any negative comments on the moral stature or sincerity of the student in any public setting. Mathematics should and will always be the common reason that makes us here. I hope to clarify, by posting the entry I did not intend to attract any public attention against any individual. The focus of the original letter was to address some possible issues of our program and discuss the possible improvements that can be made.  I am very sorry if what I have posted has caused any unpleasant consequences.
