This means the “Go Along To Get Along Crew”
Any person or group of people who don’t like to stand up for anything , rock the boat, or speak Truth to power.
They are on the go along to get along crew.
They will deny their own experience of common sense or eye witness accounts in order to stay in the socially acceptable non threatening intellectual stance.
Even in the face of clear corruption many try to justify it rather than confront it because it’s easier to be on the Gatga Crew than speak truth to power.
