I hear what you're saying, and can agree with some of where you're coming from. But I think you might be misunderstanding how an open forum works in the less than ideal "real world."
When you post on an internet forum such as this one, the topic is
yours to choose, but it then becomes
anybody else who participates to discuss. You don't get to take ownership of a thread once it's posted. Nobody gets paid to consult around here. So they're free to take any question anywhere they want.
You have the option of ignoring anything you don't care to read; or disregard any question you don't want to answer. As does everybody else who participates.
Many times what you may think of as a 'challenge' is merely somebody trying to get additional details, or clarify something, that they feel may be relevant in order to answer your question to the best of their ability. If entering into that sort of dialog isn't your thing, then a forum such as this one probably isn't something you want to do.
Best ask your question and roll with where it goes. If it strays to far OT from what you're looking for, you can always (politely) suggest people are getting away from your specific question. And then ask it again.
You also need to be a little open minded when it comes to hearing what people have to say. If your question is so specific that you only want an A or B recommendation from somebody who owned and played through two specific amps, odds are pretty good you'll get few if any answers. Because the likelihood of somebody having owned and played both the exact two models you're asking about is pretty small. You might only get one answer. Or none.
Being a little less confrontational ("Never ceases to amaze me...") and a little less defensive ("I am prepared for the slams, the slurs, the jabs...all of it...") might also go a small way towards keeping the open dialog flowing.
To paraphrase St. Mick: "I know...it's only TalkBass...but I like it." And as you yourself said: "Rock on..."
Hang in there and try not to let the place get to you. It is what it is.

P.S. I see myself as a perpetual student, or "lifelong learner" to use the colloquial expression. I joined TB primarily to learn, and share what I've learned second.
