I used to view NPR as a relatively unbiased source, but lost a great deal of respect for them (to the point that I now rarely listen) during Trump's presidency. I am not a Trump supporter in the slightest, but was appalled at their naked partiality.
Though, their apparent position relative to the Republican party seems to have changed drastically.
This was before 9/11 but that week I knew we would be going to war in Afghanistan because overnight the left-leaning pundits were speaking in solidarity with fox news talking points. This really disillusioned NPR for me, and I had been an avid listener for 10 years at that point.
I really only see superficial differences between the two sides of the media at this point.
