You're mocking Brody for accepting anecdotal testimony as evidence, in part because she ordinarily derides anecdotal evidence as insufficient. You identify this as irony.
Either anecdotes are fine to report, or they aren't.
Obviously, the answer is that anecdotes
are certainly fine to report, but they just as certainly can't be taken as the sole evidence in support of a claim. To this end, Brody has erred significantly by offering up a personally significant anecdote in place of evidence.
What strikes me (and, I would guess, trotsky) as curious is the fact that you yourself have been a fan of anecdotal testimony in this forum for years, yet now you're deriding someone who has also apparently embraced the "value" of anecdote.
The more consistent approach IMO would be for you to say something like "I have realized that anecdotal testimony is no substitute for actual evidence, and Brody is therefore wrong for mistaking anecdote for evidence."
Failing that, you could instead say something like "as an advocate for anecdotal testimony, I applaud Brody's decision to accept anecdote as evidence."
Having said that, I actually do think it is worth reporting that a breathing technique seems to help asthma. But this should have been interesting to report whether or not it helped a friend of hers.
This is basically correct, as long as it is made clear that the breathing technique
seems to help asthma, rather than making a definitive statement along those lines. Brody's anecdote--though insufficient to prove the technique on its own--may spur others to undertake a more formal study of the technique.
