There used to be a time when referees weren't so sensitive. They understood that in the heat of the moment, competitors are going to be emotional. Officials nowadays are quick with a whistle or a technical for the smallest complaints or reactions.
Snowflake refs ruined a classic Thunder-Spurs game with a technical foul that was neither necessary nor warranted. They are the definition of snowflakes.
Referees might be quick to a whistle, but it's only because players are testing their patience constantly. While players complain they can't have a conversation with refs anymore, they also complain about every single call for the entirety of the game.
Referees aren't perfect, but they don't get every call wrong. That kind of whining is grating and unprofessional. The referees are just doing their jobs. They aren't soft.
