African american problems were bigger than those women were facing, because women faced discrimination in the workplace and stuff like that etc , however african americans faced problems in all aspects of what make up a person. So african americans had to take other means of trying fight for their rights as malcolm x once said, “by any means necessary” so that leads me to my next point.. african americans used 2 different tactics like civil disobedience and a more militant type of strategy. Civil disobedience was the act of going on marches and organizint sit ins etc, but in a peaceful way and was lead by marthin luther king. However the more militant movement included violence etc, you name it and that was lead by malcolm x. Women were able to get their way through with things like the feminist movement and the civila rights act of 1964 which included title 9 that prohibited discrimination in the workplace despite of race, gender, ect.
It entails being out of touch with reality, where your optimism isn't grounded in comparison to the situation you're in.
For example, imagine climbing Mount Everest and you underestimate the weather, which are underestimating obstacles and risks.
im pretty sure this is true but to be safe just check with some more people.
