The reason it's difficult for majority group members to be inclusive is that they simply don't believe the experiences of people from underrepresented groups.
They view everyone's experience through the same lens – their own!
When they hear someone else's experience, they apply the perspective of their own lived experience, realize that the two experiences don't match up, then dismiss the other person's lived experience because it doesn't align with their own.
One of the main reasons for this is that people don't consume content and media that provides a wide range of perspectives from people "not like them."
If I'm a White man and I've never read a book by a Black person, listened to a podcast by a Black person, or go to an event centering Black people, I miss out on the dynamism and nuance and specificity of the Black experience.
I then bring this lack of exposure and lack of understanding to my interactions with Black people in the workplace and I am unable to appreciate and empathize with the experiences that Black people share.
It's an unending spiraling, devolving, perpetuating loop that always starts and ends in the same place.
A place that centers White experiences, and marginalizes any and all Black experiences.
Break the loop. Educate yourself. Do better.
