Avram, thanks for correcting. Last “inappropriate” on discussions with Hashem was meant to be opposite, of course. R Yohanan’s remark to Resh Lakish seems to be inappropriate given that it lead to death and insanity of both … If there are other opinion, I’ll be happy to listen.
1a2b3c, thanks for the brochos!
This is a good example how ad hominems start – you see one typo or unclear thought (and there are lots of them in an informal formal) – and make assumptions about the person you do not know personally. If you were to hear the same from your hevrusa, you would just correct him without thinking much. Humanity will eventually develop better attitudes towards online discussions. As an example, I see my kids easily doing quality shopping online. They quickly take review in – which ones are fake, which ones are by not knowledgeable or stable people, etc.
We have an example of this in Hagada: both chacham and rasha say lachem “to you”. Difference is that chacham’s other words are respectful and knowledgeable. I would not be surprised that chacham would get dental injuries in a modern online forum.
