Want to play "Guess what libs would say to cope with this"?
My suggestions are:
"They were all put through inhumane training regiments and others were starved so the athletes could be fed."
And/or
"Their families were held hostage and if they had lost they would be forced to watch them be executed."
Also, not the only match the team has won. They're on a pretty nice streak with wins and ties. Notably also won against Japan. There's goal highlight videos on YouTube on an AFC channel
My worry is that they might claim they were all trans and combine transphobia with their racism.
I can't remember the name of the creator but I once saw this YT vid of someone going to the DPRK and visiting a football school. It was just a normal school. The only inhumane thing happening was that they allowed kids to walk around in Man U jerseys.
