As far as writing style goes, the quote seems awkward and more relevant to the illusion of transparency than strawmanning.

I would suggest that a technique to avoid accidentally strawmanning someone

Could work. The old "break it so much that you can no longer overlook how broken it is".

Note that even if it works 100%, it certainly doesn't solve the problem of strawmanning. My guess is that if you manage to notice that the situation calls for some correction or technique in the first place, you're 90% of the way there anyway.

Of course every bit of help matters, so probably worth keeping this trick around - thanks.

(I've tried it now on your post and it wasn't all that helpful... maybe I'll have more luck with it the next time :D)
