Previously, I apologize if what I will write here is not important and maybe childish. But to me this is an unhealthy discussion.

So I commented on the thread created by Not your key not your BTC. I commented my opinion, but he fired back by calling me "kid" without offering a clear argument and kept at it until perhaps I had taken the subject off-topic. I know I was wrong but I don't think what he did was ethical to discuss with the term “kid” which I think was purposely done to belittle me.

The discussion starts here:

Is this a normal thing in this forum discussion? I have nothing against differences of opinion, but I think there is no need to insult the interlocutor with insults for which there is no clear reason.
