With his father and siblings watching and cheering from the sidewalk out front, transgender high school student Issak Wolfe attended his prom.

The Red Lion Area High School student wore a magenta paisley tuxedo and bow tie.

His girlfriend Taylor Thomas in a black dress accompanied him, as they entered the Valencia Ballroom in York.

This simple moment almost didn't happen.

An Internet post by Taylor criticizing principal Mark Shue for denying Wolfe the opportunity to run for prom king resulted in a short-lived threat from the school to ban her from the event.

After Taylor agreed to change the post, the York County school relented, said William Stambaugh, Isaak's father.

The American Civil Liberties Union has been assisting Issak in his dealings with school.

Sara Mullen associate director of the ACLU of Pennsylvania, even went so far as to send this email to PennLive.com in response to a request for an interview with Issak:

Stambaugh, agreed to speak briefly to PennLive.com after seeing his child into the prom.

In talking about Issak, Stambaugh, still often slips and uses a female pronoun.

"That's my son who was born my daughter and now she is my son. She'll be going through the physical transition in the coming years. She has transitioned socially in the last two years from the time she was 16," he said.

Stambaugh said Issak and he are more or less happy now that the prom was underway.

"I was upset at first because of the change from prom king to prom queen. I went to the principal and we spoke. We were at loggerheads, but it was cordial."

Stambaugh said it was entirely Issak's idea to contact the ACLU.

"I am big fan of the ACLU and when she decided to look them up, I thought that was very cool." The school did not allow Issak to run for prom king but did allow Taylor to attend as his date.

Stambaugh came Saturday night because of rumors that protesters may be present or some other hostility may occur at the prom. He was pleased to find that was not the case.

"I wanted to see how everything went. There were some rumors floating around. They were outrageous and as you can see none of them were true."

Some of the frustration with the situation could be heard earlier in the night at nearby restaurant Maewyn's, where many students gathered for dinner before the prom.

Six students approached separately by PennLive.com declined to give interviews with all noting that they were doing so because they felt Issak's efforts to run for prom king marred the prom by distracting attention from the event.

Issak's issues with his high school are not yet over.

Next up graduation.

The school and Issak assisted by the ACLU are working on what name will be read out and the clothes he will wear at the event.

At Red Lion, the men graduate in black and the women in gold. Issak wants to wear black. He also wants the name used that he identifies by: Issak Oliver Wolfe.

"On her birth certificate -- as you can see I am still going pronoun crazy -- her birth name Sierra Liberty Stambaugh," her father says. "All we really want is the school to create a policy and write it down, so there is no discrimination against transgendered."

For this night, however, Stambaugh is happy that his son and date were able to go to the prom.
