Some unnamed professional philosophers of the blogosphere have been known to make arguments like this:
"It is just so obvious that Calvinism is false; because it is obvious that that God could not be good on any understanding of the word."
When you offer possible reasons why their confidence is misplaced, that is met with a claim like this:
"Uh, well, I just don't have those intuitions" (where this ends debate).
Ed Feser recently blogged on the penchant of philosophers to make the "it's just so obvious" move. This is the offensive counterpart to the number one defensive argument made by, frequently, the same philosophers, i.e., the "I just don't have those intuitions" (said as you interlace your fingers, rest them on your chest, lean back in your chair, pooch out your lips, shake your head, slowly, and say, "I just don't have those intuitions") counter-argument.
To get a visual image, I'll paste in a couple pictures of what people typically look like when making these moves so you know how to spot it:
"Look, it's just so obvious"
"Nah, I just don't have those intuitions"
