I used the word "dangerous", not "controversial". In the past, you could have a controversial opinion online without risking your livelyhood and safety. No longer.
The conservative cancellation of Dixie Chicks in 2003 would seem to suggest otherwise. From wikipedia "At a 2003 performance in London, Natalie Maines of the American country band the Dixie Chicks, now known as the Chicks, made a statement criticizing President George W. Bush and the imminent Allied invasion of Iraq. The criticism led to backlash from country listeners, who were mostly right-wing and supported the war. The Dixie Chicks were blacklisted by thousands of country radio stations, and the band members received death threats."
