It’s long been accepted that using profanity in private is “normal”. It was no big deal when hot mics picked up taboo words spoken by politicians in circumstances that were intended to be private (e.g. Cheney’s “major league asshole” or Biden’s “big fuckin’ deal”. Until fairly recently it was not at all common for it to be used in political broadcasts, speeches and interviews. Hell, bitch, damn, ass etc have occasionally been given an airing by politicians, but It seems to me that for shit and fuck, in the USA in 2019, the dam was broken or the ribbon was cut.
Donald Trump, Feb 2019, NYT interview
“You know, you had governors and senators, you know they were all good until I beat the shit out of them, O.K.?”
Donald Trump, Oct 2019, Campaign rally
“They know they can’t win an election so they are pursuing an illegal, invalid, and unconstitutional bullshit impeachment.”
Cory Booker, Aug 2019, Twitter
“Such a bullshit soup of ineffective words”
Beto O’Rourke, Aug 2019, to reporters
“Uh, what do you think? You know the shit he’s been saying. He’s been calling Mexican immigrants rapists and criminals. I don’t know. Like, members of the press: What the fuck?”
Rashida Tlaib, Jan 2019, addressing a MoveOn event
“Baby they don’t, because we’re gonna go in there and we’re gonna impeach the motherfucker!”
Trump has gone there before 2019: he had previously told a rally, in regard to China, “Listen you motherfuckers, we’re going to tax you 25 percent!” In 2016, he said, ‘I would bomb the shit out of ’em’.”
It seems that this year, others have got in on the act.
