I will stand by my assessment
Then you go right ahead and stand by your assessment if that floats your boat. As for me, I'll criticize him anytime I feel he deserves it. As an American I have that right and I will exercise it at my discretion. I do not ask, by your leave, before I open my mouth to give my opinion. You don't like my opinion-tough. Then ignore it.
Not to worry, I'll ignore not only your opinion but you as well.
