Angel Locsin said the Department of Education must address bad conduct and discrimination, the "more relevant issue" at hand.
Locsin was replying to the DepEd Occidental Mindoro's apology over a teaching aid where she was described as "obese." The document went viral just as the actress was helping typhoon relief efforts.
"I intended to ignore the issue, but when I read DepEd's statement, teka lang," Locsin wrote on Instagram.
"What bothers me most is that apart from teaching incorrect grammar to students, DepEd seems unaffected that the said teacher is teaching bad conduct and sowing discrimination among the children," she said.
"Anong mangyayare sa future kung ang mga kabataan ay tinuturuan ng pambabastos at pangungutya sa kapwa?" she said.
The document was made by the teacher for a Grade 10 MAPEH class and was not developed by the DepEd central office, the DepEd Occidental Mindoro said.
"This is the more relevant issue DepEd that you should be held accountable and must correct. Sa inyo nakasalalay ang pagasa ng ating milyon-milyong kabataan," she said.
The DepEd statement also said the matter would be given "serious attention" as it appealed to the public to spare the teacher for attacks.
