I have to ask, why a site like Breitbart which has broken a lot of substantive stories would be banned? I’ve seen less credible left leaning sites on HN. I’m hoping there is a really good reason because right now I am concerned.

Because most submissions have been off-topic or otherwise against the site guidelines. Same reason why we'd ban any site.

Utterly bullshit.

HN is part of the liberal groupthink.

Fuck your lies you loser.

Well, let's see what Wikipedia has to say about Breitbart's history...

'Breitbart News Network (known commonly as Breitbart News, Breitbart or Breitbart.com) is a far-right[6] syndicated American news, opinion and commentary[7][8] website founded in mid-2007 by conservative commentator Andrew Breitbart, who conceived it as "the Huffington Post of the right."[4][9][10] Its journalists are widely considered to be ideologically driven, and some of its content has been called misogynistic, xenophobic, and racist by liberals and many traditional conservatives alike.[11] The site has published a number of falsehoods, conspiracy theories,[12][13][14][15][16] and intentionally misleading stories.[17][18]

'Breitbart News aligned with the alt-right under the management of former executive chairman Steve Bannon,[19] who declared the website "the platform for the alt-right" in 2016.[20] In 2016, Breitbart News became a virtual rallying spot for supporters of Donald Trump's 2016 presidential campaign.[11] The company's management, together with former staff member Milo Yiannopoulos, solicited ideas for stories from, and worked to advance and market ideas of, neo-Nazi and white supremacist groups and individuals.[21][22] After the election, more than 2,000 organizations removed Breitbart News from ad buys following Internet activism campaigns denouncing the site's controversial positions.[23][24][25][26]'

So... pretty low credibility. They break substantive stories when they're useful to their agenda, but also break false stories when they're useful to their agenda. I'm curious what you consider to be a 'less credible left leaning site'?
