Perhaps you should reconsider. Her article directly addresses this type of response.

"Learn to listen to your discomfort. Sometimes I find myself reading something that makes me think, “I respect this person, but would be uncomfortable holding that opinion myself.” In such cases, it’s worthwhile thinking about why I find it uncomfortable. Is it someone speaking from unacknowledged privilege? If so, is this is a good moment to call them in (either in DMs or in public)? Alternatively, is it uncomfortable for me because it challenges my privilege? If so, that is worth sitting with and trying to learn from."

Same. Honestly I was surprised it took so long, given that it was an article about Twitter.

Twitter is the new tumblr

Why?

That phrasing like that is a shibboleth. (It shows the person's beliefs/political attitudes). From that statement, you can predict what the author's statements on various things will be. Or at least, it's unsurprising.

Listening to a variety of viewpoints in good faith is a good idea. Tribal, internecine discussion is usually much more predictable than that, though. I liked the term "internet of beefs" for that.

I do like the idea of recognizing that people are human, and not just political abstractions. But, I can also understand how natural the 'internet of beefs' stuff makes political abstractions the most convenient way of viewing people.

How is it relevant to the topic she is discussing?

Because a significant portion of the article relates to using Twitter as a tool to help understand people who are different from yourself. An important aspect of that is being aware of how you differ from them.

Because the author is immediately pandering to the potential twitterati reaction to his article?

Her article. As they told you in that sentence. And their byline.

(I know there's some weird campaign against pronouns but that doesn't mean that all people writing on the internet are now "him")

oops, my mistake
