Point of order has been raised. However, this is not a valid point of order, as there was no specification in either the comment to which I replied or the original article of real-world interaction as opposed to online interaction. This appears to be based on a conflation of my use of "real world" with "physical interaction" rather than "real world" vs "idealized abstraction". In this case, the point was that the parent is describing the idealized form of argument people should engage in as opposed to how people actually engage in argument.
Therefore, the point of order is not sustained.
The charitable interpretation (see first comment) stands, though. It remains that the motivation on the internet, like the motivation in a comedy club, is not a reflection of the motivation found elsewhere. The venue is significant.
