When talking about potentially inflammatory topics on the web, expecting the reader to "read between the lines" as you say is probably never a workable idea as there can be and are enough potential speakers across the entire spectrum of opinion that any intended meaning could be possible and potentially valid for "reading between the lines" (hence Poe's Law[0] and other challenges in the discussion of complex topics on the web when the range of speaker opinions and audience opinions is large and unknown).
No one ever expects Poe's law to apply to their own sarcasm, but unfortunately it always does.
