It's not just that your comment had no value, it had negative value. If it only had no value, I would have done as you said, downvoted and moved on. But since it's existence was a detraction, I felt it was important enough to attempt to mitigate the propagation of potential misinformation.

I do apologize that adding the bit of "... hubris that your opinion matters" came across rather harshly and was unneeded to my point.
