Because you said what I wrote was "stupid"― which is hostile and quick judgement. That is a strong word to use against someone who is not stupid. What you do you think Satoshi would have done had you said he wrote something stupid? He would have roasted you, the same as he did to Daniel Larimer (the developer of Bitshares and Steem).

Discussion can be cordial or violent. You decide. I have no problem with cordial debate.

It doesn't mean I am infallible. I even have made some careless decisions in my life in my youth which can be characterized as stupid. But I don't think I often (if ever) have written stupid comments on serious topics on this forum. Some may totally disagree with my position (and that can often be to lack of understanding of each sides' views), but that doesn't mean it is proven that I wrote something stupid.
