Writing Trauma and Respect

I am a nineteen year old psychology student and it is very interesting , the amount of things you hear is highly intense. The information you learn makes you uncomfortable but yet intrigued. Now there are certain things in a psychology class that will always happen. Trauma will always be brought up, it will never not happen. Although trauma will be brough up it is still important to respect the fact that people will have triggers with certain topics. It is also important to respect peoples writing and trauma. The reason for me writing this is because something has been on my mind about the last day or my last program. As some background information, I was in a program about psychology ,sociology and creative writing. We would right about something that would relate to what we learned. On the last day of class every person went around and read something they wrote at any point in their life. My boyfriend read a very emotional and powerful writing he did ( I never cry while reading anything however, this made me cry). He did trigger and content warnings like we were told to do by the professor. We let 30 seconds past for people to get up and leave the room if needed. Almost the whole class left the room, maybe 10 people stayed including me. My other boyfriend left the room ( I am poly) and what he told me when we were done with class made me livid. He told me someone was talking about how the " trigger warnings were too much" and " I didn't put any triggers in my story so no one would have to leave". He talked shit about my boyfriends writing while he did not want anyone to talk shit about him. HE wanted respect from the class while HE did not respect anyone. We never confronted him for this because my boyfriend asked me not too. My main thing is that if people want respect while reading something personal or just want respect in general then they should respect others as well. Its like the kindergarten saying " Treat people the way you want to be treated".
