I'd go farther and say that it is disheartening. It also seems to be completely aligned with the post-modernist way of evaluating/describing the world.
Nothing to do with post modernism, it's a version of Marxism that is compatible with capitalism. Post modernists can't be ideologues by definition. Intersectionality is very much an ideology. People who believe that don't ask question, they do finger pointing and public shaming to try to change and control public discourse. It's very reminiscent of the soviet union era, except it doesn't come from the state but a group of people that hold a certain power of influence, ironically.
Im open to hearing an alternative argument instead of just folks downvoting. What do you think is inaccurate or misleading here?
All speech has both subjective emotive content ("power") and objective factual content ("truth"), and the interplay between them is part of what makes speech effective. In times of hegemony, though, the "power" content of speech is downplayed. Power relations within society are taken for granted, and it's pointless to challenge them, because the best case is that your words will be discounted as crazy and the worst case is that that power will be exercised against you, potentially with life-ending consequences. Think about speaking out against a totalitarian government, or being a communist during the McCarthy era.
In times of multipolarity, the "truth" aspect of speech is downplayed, and discourse is all about power. Think of nationalism in the 1870s, or yellow journalism in the early 1900s (right as British hegemony was collapsing into the multipolar world that led up to WW1). Papers would publish plenty of stories that simply weren't true, but the point wasn't truth: it was to boost their circulation numbers and amass more power and influence in a world that was rapidly collapsing into a system of warring powers.
Trump, SJWs, white nationalists, MRAs, cryptocurrency advocates, anti-vaxxers, Russian cyber-trolls, and Democratic Socialists are all other instances of this phenomena: they are small splinter groups vying for mindshare because they see that the existing power structure is collapsing and will leave behind a vacuum, and they all distort the "truth" (which was always distorted before by power relations, but not to this extent) in a bid to gain more followers. Some corporations are catching on, and this FedEx statement is an example of this: note that they posted it as an open letter, on their own company blog, rather than as a press release. They don't care whether the NYTimes actually accepts their debate or not, they want to make the public statement to undermine the legitimacy of the NYTimes as a source of truth itself.
