I went back to the article and found the problem, right here, where she ties together being uncivil in the inevitable human interactions of our day (e.g., bringing your bad energy into the dog park) with how you choose to build community beyond that, implicitly comparing her choices with yours. That's the default tone of the self-congratulatory prig.

Yes, it is good to stretch your comfort zone to meet new people and help build community without choosing situations that would make you miserable. Strangers? Ipso facto good? Rubbish. She may have scared more people off getting out than she inspired as some misguided soul is right now looking at Meetups, choosing "random after dark random networking with drinks" over the LUG. Sure, join the political group or the book club if it inspires you.

"Years ago, I was habitually late. “I can’t help it!” I declared to an expert in time management (I’d turned my effort to reform into a magazine article, as writers do, which gave me the excuse to seek professional help)."

And by the way, showing up late is garden variety selfish behavior that directly harms at least one other actual human being. The author managed to slip in a less insidious self congratulations here, too, a lot of work for one sentence.
