If someone is taking one specific point and replying to that while ignoring how it fits into the overall argument, then it seems to me that they are not reading to understand, but are picking out "gotcha" points to reply to.
Working with the key points in an overall argument is fine, but far too many of these posts attempt to respond to all arguments, consequential or not. Often at some length. The responses to those posts can be even worse.
This is not the best format for such a debate style.
I prefer to stick to the main points and ignore the side trails where possible.
This may seem like selecting "gotcha" points but it is actually being more selective and focused.
