You may have also noticed that those types of threads that seek to avoid debate generally flame out rather quickly with limited response.
That's because when a member see's a statement such as that, they quickly realize that the OP is not looking for discussion, but is just trying to
bait people into their trap.
Most often the types of threads you're talking about don't last very long. Sometimes they do though and I can see how it can be rather frustrating.
Of course, you could always do what I do in that case, and ignore them.
