Are you aware of the meaning of the phrase "it sounds like"? Because comments like this just make the whole discussion-in-the-web thing a rather unpleasant experience.
Not sure how the meaning of the phrase "it sounds like" plays into this.
My point was that you accuse the parent of arrogance, while he was merely mirroring/responding to the arrogant tone in your comment (in the lines I've quoted).
That is, my point wasn't that you made an absolute claim ("your code is X") that was false. If that was my claim, yes, you could refute it by saying "I only said that it sounds like X is the case, I didn't make an absolute claim".
But my point was rather that the tone in your comment was arrogant.
"Your code base simply wasn't too big after all" is equally arrogant whether prefixed with "sounds like" or not.
It makes assumptions about the size of the other person's codebases, and it arrogantly implies that they don't see what they see because they haven't worked in as large codebases as you have.
