Dan Froomkin — one of my favourite American commentators — offers several suggestions for the New York Times style guide. Here are a few published at presswatchers.org:

Baseless — “Baseless” means lacking foundation in fact. Like “lack of evidence,” “no clear evidence,” or “unproven,” it does not carry with it any implication of deception. Do not use these terms to contextualize a claim that is false, specious, spurious, and/or intentionally deceptive. It is insufficient.

Improper usage:

• “baseless claims of voter fraud.” (Jan. 5, 2024)
• “baseless theories that Mr. Trump had been the actual winner of the election.” (Aug. 15, 2023)

Bold – Bold is a generally positive word. It means confident and courageous. Do not use it as a euphemism for outrageous, illegal, immoral, fascist, etc.

Proper usage:

• “A Package of Bold Laws Puts Michigan on a Fast Track to Renewable Energy” (Nov.8, 2023)

Improper usage:

• “Trump’s Boldest Argument Yet: Immunity From Prosecution for Assassinations” (Jan. 10, 2024)

Conservative – Do not use “conservative” to describe people who are not conservative. For instance: extremists, Christian nationalists, and authoritarians are not conservative. Conservatives believe in limited government, states’ rights, personal freedom, and personal integrity. Donald Trump is not a conservative; neither is the movement he leads; and neither, anymore, is the party he leads – especially not its right flank. For MAGA in general — and for the anti-gay, anti-immigrant movement in particular — use instead, far-right, extreme right, extremist, Christian nationalist, or fascist, and describe their preferred policies as regressive, authoritarian, radical, or intolerant.

Improper usage:

• “Conservatives thrust the House back into chaos on Wednesday, grinding business to a halt in protest of the spending deal Speaker Mike Johnson struck with Democrats to avert a government shutdown and leaving the funding package in limbo.” (Jan. 10, 2024)
• “Do you support the right of a woman who is just seconds away from birthing a healthy child to have an abortion?” [then-Rep. Mike Johnson] asked at a Judiciary Committee hearing….The exchange reflected the lawmaker’s deeply conservative views, particularly on social issues, and his tendency to express them in inflammatory ways.” (Oct. 25, 2023)

Proper usage:

• “Ultraconservative House Republicans have panned the $1.66 trillion agreement Johnson made with Senator Chuck Schumer…. ‘This is a total failure,’ the far-right House Freedom Caucus…. wrote on social media…. The backlash from the extreme right….” (Jan. 8, 2024)

Evangelical – When you are writing about racist, right-wing white Christians who consider themselves a persecuted minority, do not use “evangelical” as shorthand. They are not necessarily evangelical. Call them racist.

Improper usage:

• “Being evangelical [is] often used to describe a cultural and political identity: one in which Christians are considered a persecuted minority, traditional institutions are viewed skeptically and Mr. Trump looms large.” (Jan. 8, 2024)

Moderate – Do not describe someone as moderate just because on one or two issues there is some daylight between them and the extremists in their party. A moderate is someone who represents centrist views, who has principles that trump partisanship. There are currently no moderate elected officials among House Republicans.

Racist and Racism — Identify racist acts and people straightforwardly. The great replacement theory is racist. The view that white European immigrants are superior to Africans or Asians is racist. The view that immigrants are “poisoning the blood” of the country is racist. Do not use “racially charged” and “racially tinged“.
