A few more FGCAs. Some of these aren't really arguments, but anyone mounting an FGCA is unlikely to be concerned about epistemological propriety, and all of these things can be used together in support of each other.

1. "Check your privilege."

2. "Check your premises."

3. Psychologising the opposition.

4. "This is settled science."

5. Emphasis and reassertion of the thesis.

6. "Oh. My. God."

7. "*facepalm*"

8. "Ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha!"

9. Satire.

10. Parody.

11. Pretty much anything, said in your own echo chamber. NB. Link to your allies' actual postings, but not to your enemies'. A link to the top of their blog is better.

12. Cite some other blogger and say they've completely eviscerated the enemy.

13. Irregular verbs. ("We are right/You are wrong." "These studies prove/Those studies are flawed." "We have the support of.../You are in the pocket of...")

And a Fully General way of generating all of these and more: bottom-lining. Nail your desired conclusion to a wall marked "TRUE" and your opponents' to a wall marked "FALSE", and ask the virtual outcome pump in your head to fill in the empty space on the walls. There is no conclusion, however absurd or repellent, that you cannot do this with. The smarter and better educated you are, the more puzzle pieces you have available to play with and the more easily you can invent new ways to put them together.
