That is what the coffee house is for: however, as this is a debate forum with points being backed up with evidence or reasoned argument not using that style can pull threads way off track.
It used to be that there was a hard code post limit to threads and after 300 posts the thread would close and so this led to a need to be specific and to the point.
Although that is no longer true it is still the culture of this board.
In coffee house you can jump around the discussion much more freely but not in the normal threads.
Look at it this way: imgine if you were giving a presentation about a subject that was really important to you but people kept asking irrelevant questions: how much of that could anyone take.
That's what happens here; we stay on topic as best as we can.
One to look out for is when someone starts a thread about ID but then goes on about evolution and nothing else. Or starts. Topic about evolution but goes off on a tangent a out abiogenesis.
Do you have a link to the post that made you feel this way?
