Michael Hirsh stepped down from his editorial post at Politico's weekly magazine on Tuesday after publishing the home addresses of white supremacist leader Richard Spencer on Facebook

The national editor of Politico's weekly news magazine resigned his position on Tuesday after he came under fire for advocating baseball-bat attacks on a white supremacist leader – and publishing the address of the man's two homes.

Michael Hirsh stepped down just hours after writing on Twitter that Americans should 'stop whining about Richard B. Spencer,' whom he called a 'Nazi,' and exercise your rights as decent Americans.'

'Here are his home addresses,' Hirsh added, providing one in Montana and another in a northern Virginia suburb of Washington, D.C.

He also tweeted: 'I think it's good that Neo-Nazi Richard Spencer is moving to Washington. It's important that we know where he lives.'

After a dissented questioned the value of posting Spencer's addresses, Hirsh responded that he wasn't thinking about writing 'a f***ing letter,' and then suggested baseball-bat vigilantism

Spencer's Facebook post drew a response from investment lawyer Doug Widmann.

'[I] completely agree we should mobilize against his hateful ideas, but what does knowing his home addresses do?' Widmann asked. 'Send a letter? Confront him in person? Seems like counter-speech is the main thing we can do. You can call it 'whining' but I'm not sure that's fair or constructive.'

Hirsh's response crossed a line that put him on the wrong side of Politico's management.

'I wasn't thinking of a f***ing letter, Doug,' he wrote.

'He lives part of the time next door to me ... Our grandfathers brought baseball bats to Bund meetings. Want to join me?'

The National Policy Institute held a party in Washington where some including reality TV star Tila Tequila, right, were pictured making Nazi salutes

The Daily Caller News Foundation, which was first report on Hirsh's social media postings and his departure from Politico, noted 'Bund' referred to the German-American Bund, a 1930s-era American Nazi organization that was often attacked by 'Jewish mobsters in New York City and Newark, New Jersey, using baseball bats.'

Spencer, the white supremacist rabble-rouser who attracted Hirsh's ire, organized a party over the weekend in Washington for about 200 self-described advocates of the 'alt-right,' a designation that once signified conservative contrarians but has been hijacked by anti-Semites and other racists.

Spencer's group, the National Policy Institute, officially sponsored the event. It included moments caught on video in which attendees offered Nazi salutes.

Politico editor-in-chief John Harris and editor Carrie Budoff Brown issued a statement Tuesday afternoon, saying Hirsh's online statements were indefensible.

'These posts were clearly outside the bounds of acceptable discourse, and POLITICO editors regard them as a serious lapse of newsroom standards,' they said.
