You have to see my list of how these things go here.
Typical tactic of the left/center-left here...
Left wing Poster A makes sloppy, broad brush comment, gets called out.
Left wing Poster A makes a sloppy retort in defense
Left wing Poster B shows up and makes a different defense, gets called out for the original claim
Left wing Poster B denies ever making the original claim, even though poster B is defending it
Left wing Poster C shows up, defends original claim, defends poster B
Left wing Poster C gets called out, denies caring about the original claim, denies supporting Poster B, still wants a back and forth about the original claim.
Left wing Poster D shows up, posts a strawman meme about the attack on the original claim
The responses pretty much cease because of the web of that's developed,
Left wing Poster E calls fold
rinse and repeat
Except in the middle of some of these the three stooges engage in a multi-page slap fight.
Usually SR21 is left poster B. He comes in with a "nuh uh" defense with the knowledge that he doesn't need to defend the initial claim that's being discussed in the first place.
