"I like to say that when you see stuff like that you should give me credit for doing it intentionally, so I need to disclaim credit in this case."

"If I'd thought of it myself or even noticed it after I did it, I would have rewritten it to avert microaggression. But I'm not so fussy and fearful that I'll change it now, and I'm not such a creature of The Era of That's Not Funny that I feel that I need to strike the 'LOL.'" 

That's something I wrote in the comments to the previous post after an "LOL" directed at Jack Klompus. Klompus, reacting to my post, had written: 

The "Ah! So..." triggered me into doing an impromptu Charlie Chan impersonation. Very problematic. 

I had to look back at the post, which is about a WaPo article, "The Biden administration confirms some but not all of Trump’s Wuhan lab claims." Had I written "Ah! So..."? Yes, I'd quoted something from the article, then exclaimed: "Ah! So it's not that you've determined that any of these claims are false." The "Ah!" was independent of the "So," but the "So" directly followed, and I have inadvertently caused the "ah"/"so" combination to come into being in a post about the Chinese. 

I'm sure some of you who comment here think there's nothing even wrong with saying "Ah, so!" intentionally, even with a Charlie Chan-style intonation, but I've got to find my own balance of correctness/incorrectness. In this case, I would never purposely exclaim "Ah, so!" while talking about the Chinese or even while talking about anyone else. It's just pointlessly disrespectful. And I do mean to imply that sometimes disrespect is justified and warranted. But casual disrespect — disrespect as a go-to demeanor — is lazy, dumb, destructive, and degrading.

For a serious, critically acclaimed examination of the Charlie Chan character, read "Charlie Chan: The Untold Story of the Honorable Detective and His Rendezvous with American History" by Yunte Huang. I'd read it, but I've never watched any Charlie Chan movies, so I have no context — other than the context of hearing various Americans imitate Charlie Chan, usually by saying "Ah so" (and just meaning something like "Yes, I understand").
