There's no such thing as unbiased news. News is informed by all kinds of biases at every moment, many of which are completely innocuous and harmless, even good.
For example, most news sources refer to people in stories as men or women, and use gendered pronouns. Gender is a social construct, so recognising it implicitly in an article is a bias. An unbiased news source would refer to everyone as they/them and never present a gender identity as fact. It would always refer to people as people. Well, except for the fact that personhood is a social construct too. And so is humanity. They'd have to call everyone beings or entities. And that's bad. An unbiased news source is bad. The news should have the bias that it presents people's gender identities as facts.
What Ground News presents as unbiased stories are usually center-biased stories, not unbiased stories. And the lie that centrism is unbiased is dangerous. Every story on Ground News is equally biased, because everything is a bias. Their bias rating is a dangerous lie. Because encouraging people to see the most common view as unbiased causes people to go along with whatever view is common, even if it's bad. Even if, for example, the government has been taken over by Nazis. Bias confirmation machines like Ground News are always dangerous, but they're especially dangerous when fascism begins to be normalised, which is the struggle we're currently facing.
