Handgun "carry" is commonly understood to mean "in an openly visible holster". What you admit doing is a lot closer to "brandishing", which is a justified offense just about anywhere your life is not in immediate danger or otherwise not legally actively seeking to shoot something.
Yeah, if you're wandering around with pistol in hand (or, as referenced elsewhere, AK-47 pistol altered to look like a toy) and generally understood by all (yourself included) to be doing so for the purpose of attracting attention, then you're not going to get a lot of support around here.
The law in the town referenced required the pistol to be carried “in the hand”. Kwikrnu was showcasing the absurdity of the law. If he had actually broken any law, it would be all over the net. He hasn't. We have way too many laws. I applaud someone who is willing to take a little risk to point out absurd laws.
