I didn't have much of a problem with the GP's mildly dismissive comment about Hickey's talks, nor was I hugely concerned that you opened a can of worms about it. What I would, however, like to remark on how your comment forced me to think of you as a complete dumbass who has no business mingling with people who, like most of us, get paid for our ability to think logically.
In your "clever" attempt at irony, you ask your parent about his own, presumably better talks. Please take a moment to reflect on how utterly stupid this line of attack is!
Give up? OK, here's the explanation, by analogy: I'm completely incapable of building an automobile. Yet, having driven both, I'm qualified to comment that a Geo Prizm is an underpowered, shoddily constructed car - at least when compared to my Lexus. A talk is a product created for the benefit of an audience, and as the consumers of such a service, the audience - including the GP - is probably best qualified to judge it. To imply that only a producer of talks may have an opinion on a talk is shockingly stupid.
Before you attempt another such put-down, please consider how it will reflect on you, and whether it might not be more sensible to keep your mouth shut!
