People who tell marginalized groups that the world is not as prejudiced as they think it is are generally a subset of the same people who make the world a deeply prejudiced place.
There are those who consciously and openly pour abuse and ignorance into the world and then there are those whose ignorance enables them to unwittingly pour abuse and ignorance into the world.
The first are openly proud of abuse while the latter feel compelled to gaslight others into believing their false innocence.
