You're taking that quote completely out of context. As you will recall, you disputed the time of sunrise and/or the time that the planet Venus rose at a particular location on a particular date. I linked you to some software that you could use to verify for yourself that the times I had given were correct. Despite that, and without doing any checking for yourself, you continued to insist that I was wrong. In other words, you continued to insist on a falsehood, in spite of being presented with clear evidence showing that falsehood, that you could confirm for yourself with only a little effort.
Like I said at the time, you can only lead a horse to water. If he is too stupid to drink the water that is offered, there's really nothing more you can do to help.
To summarise: my "idiot" comment, which you quoted, referred to nobody else but you, and to nothing else but the specific matter that we were debating at the time. It remains a valid comment. You have never conceded that I was right all along. To my knowledge, you never did download any software or do any checking for yourself. What you did was you literally chose not to look at the evidence, because it didn't suit your bias.
