I was being sarcastic. The mere act of a government giving people money or otherwise interfering with contracts does not make that government "socialist" any more than walking to the grocery store makes you a triathlete. A hardcore socialist would probably scoff at the very concept of a "government relieving student debt" as something that shouldn't be possible or even make sense in a socialist society.
I would expect a socialist to be onboard with cancelling student debt though. They'd just want it to be part of the government taking over education more completely. Schooling wouldn't be something one pays for at all because the government would be responsible for providing it (and deciding who has access to it).
