Why society is unfair with teen male?

The way in which my son is branded and spoken of is very exaggerated and unfair. Through the past month he experienced a difficult time going through a split with his fellow peer. He tried to reach for help through his teachers and a social worker, hoping to find a way to cope and instead he was abused with statements such as “this young man is experiencing significant mental health issues.” This all occurred because he dared to cry and show sorrow when he was told by the peer that she felt uncomfortable talking to him. Furthermore, after this incident that occurred on March 24, 2014, the peer contacted my son first on the same day.
Approximately two weeks after, I was phoned at work by the principal, informing me that she would call the police if I was not able to come and pick up my son after school. I asked her to wait for me around 5-10 minutes, and moments after we had finished our conversation, she called the police nonetheless. She had also told my son that she would not call the police unless he left the school. He did not leave and the police was still called. My son was escorted by the police to the ER per the principal’s statement that my son was having a “suicidal crisis.” The principal came to this conclusion based on a Facebook conversation between my son and the peer which was shown to the principal by the peer. Recently, I read the messages in which my son stated “I’m always going to be there for you.” These words obviously show no intentions to commit suicide.
My son was assessed by the ER team by Dr. Doey, a psychiatrist at Hôtel-Dieu Grace Hospital where he was escorted by the police. He was released in the same night from the hospital as the ER team claimed that he was not in a crisis. The psychiatrist had not considered he needed any follow-up appointments or medication. He was not diagnosed with ant mental health illness. I communicated all of the results to the principal; however, she didn’t accept my son to go back to school for a week
