The Texas student is reportedly being bullied after his girlfriend was dismissed as a beard.

A Texas father is speaking out after a teacher allegedly labeled his son as gay.

The unnamed father says his teenage son is now being bullied at Nixon-Smiley High School because his teacher told his girlfriend in front of a classroom full of students that he is gay and only using her as a cover.

“I don’t want it swept under the rug,” the determined dad tells NBC affiliate News 4 San Antonio.

“When you say something like that in open class kids are going to talk and they’re going to go with it.”

“She assumed it because of the way he looks,” he continues, referring to his son’s appearance and attire. “He’s a well-mannered kid, takes care of himself.”

The father insists, however, that his son is straight. “Gay or straight is not the problem here,” he clarifies. “The problem is the teacher making a comment causing bullying in a school.”

“She expects those kids to carry themselves a certain way. Shouldn’t she carry herself a certain way?”

The father, who filed a complaint with the school district, has already had a meeting with the Nixon-Smiley principal and the accused teacher, who reportedly admitted to making the comments.

“She’s apologized but I didn’t want an apology,” he says, explaining that he wants the teacher to lose her job. “What’s done is done so there’s nothing she can take back.” He is currently exploring his legal rights.

District leaders confirm they are aware of the allegations and have launched an investigation.
