I AM NOT HOMOPHOBIC .... BUT SOMETHING HAPPENED TO ME .

hey guys , i was just randomly sitting in my classroom and eating my lunch when an openly gay person comes up to me and just says " you know i am gay "? to which i said " uhmm okay i guess i dont care lol" . to which he just flipped my lunch box to the ground and said loudly " die you homophobic piece of shit " .... My classmates laughed at me and whispered about the incident, prompting me to leave the room in tears. At that moment, I felt lost and retreated to the restroom, where I cried extensively. I want to clarify that I am not homophobic; rather, I am uncomfortable with the notion of having others' beliefs imposed upon me. Therefore, I ask: was I in the wrong, or was the individual who instigated this situation at fault? also , my girlfriend went mad about this and broke up w me the same day this shit happened so yeahh...
