Not that I have any skin in the game here, but I reread these posts, and I did not find @Ch3vr0n's post rude or insulting. The comment itself - "that's nonsense for the most part" is kinda like "I wouldn't worry about it a whole lot". He then explained his reason, and, more than that, asked you where you read that. So you educated him. But to call this exchange insulting is way off the mark and only serves to fan the flames.
