I think this one is honestly my favorite:
Specifically because once you're trained to see this pattern, you start to see it everywhere. From the President to conservative media hosts, you'll always be able to see people practicing this wherever you go. Pretty much every forum you go to has these people as well, from both the left or the right - though obviously, a lot more prevalent on the right, due to the left's burning need to be
justified (the right doesn't care about justification, just about beating down "the libtards").
In particular, the oft-noted concern troll is a mixture of Never Play Defense and the title video, The Card Says Moops. Once you're trained to look for it, you'll notice that their position always seems to be "I like your ideas in general but I think you're being too extreme about it", no matter what your ideas actually
are. No matter what the issue is, they're always
concerned, not about the issue itself but about how you're handling it - hence the name. Always on the offense, and less concerned about what the issue is than about being
right, in their minds.
