You don't know what you're talking about = direct insult?

Bone has a certain style of direct questioning that I am considering adopting, not necessarily regularly. Assuming I can pull it off: not clear.

Here’s my example of the latter: the key word was explicit:

As for an example of the speculative kind, you are just saying that because [fill in the blank]. (Admittedly others do that with greater finesse. It occurred to me today that this may happen more in the IMHO forum than in GD. Which I frequent less.)

Trinopus: Perhaps the best approach is to ask during round 1. Perhaps. But I caution that motivated reasoning is a real thing. As is the related concept special pleading. Judiciously identifying such rhetorical patterns aids the fight against ignorance.
