Excellent summary of liberalism. There’s even some overlap/reinforcement among the points. Nothing to add.
The problem is that newsrooms are packed with liberal journalists who see the world through a liberal prism. There’s a lot of racial and ethnic and gender diversity in newsrooms these days,but very little ideological diversity — very little diversity of opinion. So, inside the bubble, everything to the right of center is (correctly) seen as conservative,but everything to the left of center is (incorrectly) seen as middle of the road. Liberal views, in this world, aren’t really liberal. They’re moderate. They’re reasonable. They’re mainstream.
