But it is an explanation. People use mbfc as a way to simply wrap themselves in a blanket, to excuse or feel ok about ignoring anything that feels "icky", rather than actually taking the time to read through multiple sides and sources to sift through the biased language most media platforms use, whether it's left right center up down or what-have-you.

It's basically a time-saving ignorance shield for the vast majority of people who don't really care to put the work in. Subtlety and nuance is lost in convenience.
