Two of the myths that work to keep these oppressions invisible to us (especially here in the U.S.) are 'individualism' and 'meritocracy'. The notion that your effort will allow you to achieve anything you want and the notion that those who are "on top" get there because of their merit and/or effort are two deceptive fictions that work to obscure our awareness that groups we are assigned to are pretty much the biggest factors that determine our experiences in life.
By the way, one other thing you can glean from the above image is to be able to identify which group members (on average, there will be exceptions) accurately comprehend things. In other words...the more power any group possesses the less accurate folks that belong to those groups understandings (or beliefs) will be (again, this is on average).
This next image makes me smile for a number of reasons.
For me, doing this sort of changing is really difficult, I've often failed at it...but sometimes I've managed to do it. I've also found that many/most people struggle with this sort of thing. That's why it is a good idea to be rather tentative about how strongly you embrace beliefs, especially those that aren't based on reliable and credible facts...and even then you would be wise to be aware that you may encounter information that requires you to do a re-evaluation of a belief.
This last image has to do with a big part of why beliefs are rarely changed when we encounter information that contradicts them...it's unpleasant and uncomfortable and even painful. The image uses the phrase "unlearning oppressive behaviors" which would include changing the beliefs that uphold or support those behaviors.
One of the clues that can really be useful that we may be encountering information that contradicts something erroneous (or oppressive) that we've learned is...you guessed it...feeling uncomfortable. Which...may also be a signal that we may be in the presence of something that we very much need to learn. Is it the case that we might need to move toward that which bothers or upsets us instead of away from it? Hmmm....
