I looked this up, it absolutely is a problem. People being unable to empathize with each other due to differences in the way they percieve reality is a problem. It's not that people perceive the world differently, it's the fact that it causes a lack of empathy between two or more parties that is the problem. A lack of empathy can lead to one or more parties taking action that hurts another party.
That honestly seems like a problem, especially since the world seems to be suffering from a critical lack of empathy as it is. Simply reframing or ignoring it won't make people suddenly, magically, universally empathize with each other. If anything, reframing it risks causing the problem to go unaddressed and result in larger issues down the road.
