If he's being sincere, then he isn't abusing you. He's doing what he thinks is right.
He's abusing the trust system, which is what really matters. Posting a negative trust rating for "medical misinformation" is ridiculous no matter how you look at it. This is not a hospital and whatever TECSHARE says on medical topics doesn't matter even if he prescribes us all vitamin C for AIDS treatment.
You are all sad little people desperately trying to invent any reasons possible to impugn the characters of anyone who commits the high crime of offending you, one way or another. This is a cute little good cop bad cop thing you have going here, but both ultimately pushing in the same direction.
Next time I will refrain from posting scientific studies if they upset you so much. I will also skip analogies too unless they are perfectly and exactly medically accurate to absolutely everyone's liking as well. Clearly people get their medical advice from passing mentions of diseases in internet forums, and that is obviously reckless endangerment that could result in the death of millions, possibly billions.
I mean I could have caused the extinction of the human race, I guess I should be executed for crimes against humanity for everyone's safety going forward. The galaxy itself was threatened by my reckless actions, and I should know better than to casually write a one sentence analogy about a disease to illustrate a point about something totally unrelated to medicine.
