Anti gay shirt conflict

i believe that the shirt should be allowed in the school because homosexual students get to give their view on the day of scilence and if that offends him and his religion then he should also have is view point stated.  from a legal stand point the school has speechcodes that allow them to tell the student, Harper, to remove the shirt because of the wide varity of people in the school that do support homosexuality and the struggles they go through enough to be extremly offended.  I see both points and I do not know which side to agree with.
