This just seems stupid on the part of the school or there’s got to be more to the story...
The student seemed to be a notorious whistleblower, posting remarks online that put the school in a bad light. If the harrassment is real, get a lawyer or intermediary. Don’t slam the school month after month, building tension, then wonder why they’d prefer to act as though you don’t exist.
Be what you wish, but on your own time. Don’t use the school basketball team as a platform for your LGBT ambitions. This distraction is one of the main reasons almost no team wants to deal with Michael Sams. He wears his heart and sexuality on his sleeve, so to speak.
Apparently there is.
I would bet the real story is he failed to show up for the photo shoots, and then demanded that despite that they make special accommodation to him to do another picture.
