Hi Jean, you quoted the GNU Kind Communication Guidelines already in this list: https://www.gnu.org/philosophy/kind-communication.en.html
May I draw your attention to this specific sentence: Rather than trying to have the last word, look for the times when there is no need to reply, perhaps because you already made the relevant point clear enough. >From the last 1000 messages, 174 messages come from you and the vast majority of them are not about fixing bugs or directly providing an answer, they are about sharing your opinion on something. Sometimes it is on-topic, sometimes it is not, it is hard to tell, because your message tend to be very long. I strongly suggest you try to think twice about this sentence from the GKCG before writing. Thanks, -- Bastien
