I disagree with your premise, spelling errors aside.
You are correct. My premise was hyperbole. I should have written "Gaffes are not rare on these threads and are made on different sides of arguments."
As to your description of certain types of individuals being eager to confess error, I tend to disagree, having been recently involved in a dispute. I will merely state that so as not to invoke a new exchange of words over the incident.
Involved in the topic was another individual, who was mistaken. He civilly asked for an explanation. I gave it to him citing the source and explaining his error. I did not refer to it as an error and I did not call him names for not reading or understanding what was available to him. The individual never acknowledged error, and I did not harry him for such an acknowledgement. I offered to go on and discuss a part of the controversy but received no reply. It seems to me that he did not wish to "technically" discuss the topic when given the opportunity. I also find that to be "overcooked"(not rare) on these threads.
