No, I'm not, and you're putting words in my mouth.
This:
> I have tried in the past to explain how awesome the ratio is, but it didn't go well because of dumb people.
Does not mean the same thing as this:
> I've tried in the past to explain how awesome the sqrt(2) ratio used as the basis of DIN/ISO page sizes is, but there are some very dumb people on HN.
I believe you that that's not what you intended to say. I certainly don't intend to put words into your mouth! But I think you're wrong; I suspect the vast majority on HN read your comment the way I do.
The word 'tried' implies an attempt that failed. And in the phrase "I've tried... but...", the part after the but almost always implies causality.
"I have tried in the past to explain how awesome the ratio is, but it didn't go well because of dumb people."
You are correct that you're not blaming anyone for being dumb, but you are blaming others for the explanation not going well.
