The reason this doesn't excuse her for me, is that a journalist - of any type - is supposed to absorb events, place them in their context, and convey the result to a general public.

So she may have been hired as a fashion journalist, but this shows her to not rise above a fashion writer. That is, someone who produces stories, not someone who reports on events.

Or, to put it differently: I reject the notion that fashion journalism is completely unrelated to other forms of journalism. These professions share a common core, and the actions discussed in this twitter thread show the person in question completely missing that core.
