Person attempting to justify an injustice they also suffer, without even a thought about whether it being "how it is" might actually be connected to all the people saying dumb stuff like "Well, that's just how it is."
This is one of the few acceptable ones IMO. Sometimes, something is bullshit, you know it's bullshit, everyone else knows it's bullshit, but you have no ability to fix or avoid said bullshit, so... it is what it is.
