Then why do media-bias rankings (at least the 1st source I could find) put them near the center? If anything, my perception is that PBS and NPR are a bit right leaning, except for the focus on things like diversity, which I am baffled why people seem think of as a left versus right issue. Just to clarify, not being pro-Trump does not indicate a left lean.
