Vox.com definitely does not handle the difference between opinion and news responsibly and NewsGuard should give it a negative mark. Its articles are not only biased but contain loaded questions. Yes, it has some pieces that go counter to its left-wing POV, but those are relatively few and far between. Many of its writers target perceived enemies and attribute to them the worst possible motives rather than taking a neutral or nuanced perspective. It also engages in censorship campaigns against these perceived enemies, so does not approach anything near being responsible.
