”Women who don't have children will go to prison” - High school teacher's remarks... Police investigation = South Korea

A man caused controversy by speaking about men's military service obligations during a class at a girls' high school in Incheon, South Korea, and saying, "Women of childbearing age should be sent to prison if they don't give birth."
A sex teacher is being investigated by the police. On the 23rd, the Incheon City Office of Education and others said that the teacher's comments may be considered child abuse and that they have requested a police investigation.
On the same day, the city's Board of Education, at a meeting chaired by the deputy superintendent of education, decided that Teacher A's remarks could constitute child abuse, based on the Special Act on the Punishment of Child Abuse Crimes.
The city's education department also plans to conduct an audit of teacher A and investigate whether he violated the obligation to maintain integrity.
"We will consider it together." Prior to this, a two-minute recording of a "Politics and Law" class for second-year students at a girls' high school in Incheon on the 17th of last month was posted on social media.
Teacher A previously commented on the Constitutional Court's ruling that the military bonus system is unconstitutional, "I think this is the worst decision," and added, "Men go to prison if they don't serve in the military, but women go to prison if they don't have children."
"But you won't go to prison if you don't have children," he said, adding, "(Giving birth) is not an obligation. That's why (South Korea's) birth rate is 0.67. Women who don't have children even though they are of childbearing age are not being punished.
After that, people on the Internet commented, "I question his qualifications as a teacher," "It's not right to instill biased ideas in children," and "He should be disciplined."
" Criticisms such as "What are you doing here?" arose, and the city board of education and the school immediately began an investigation after learning of the issue. Students who heard the remarks directly were said to have felt uncomfortable. One current student said via MBN:
"I think that's an exaggeration," he said, expressing his dissatisfaction.
