Wow, that really set you off! Into a long, sometimes coherent but thoroughly convoluted and torturous rant.

You've just proven what I said but added to being one of the grammar police to believing you're being attacked. So, that's your dukkha. And being one who feels the need to correct others in public rather than merely sending a private note then you want the attention of being right one. Being right makes you just that: right.

Your catch on an error in grammar was right. O, you had the right answer. Congratulations, you were right.
