Was involved in an RP on another forum.

Had someone CC/Meta Game in order to prevent me from Meta Gaming, which is a hilarious excuse in my opinion.

Here's what happened, bear in mind his character had already threatened to kill everyone in the RP and attempted to assassinate one of two characters in command, and several characters had pointed out that they did not trust him.

He posted that he, in the same room as every character in the RP but without anyone (save one character who he decided was cool with it) noticing, pulled his gun out, stripped the magazine, ejected the round from the chamber, pointed it at my character, and pulled the trigger.  Then he put the gun away with a smirk and gave a speech.

When I pointed out that he had CC'd everyone in the room in doing that, most of them implicitly, my character and the unnamed character who noticed but did nothing about it explicitly, he explained that he did it to prevent me from interrupting his actions, which would have been meta-gaming.

Ultimately I wish I'd just let it come to pass to see what came of it, but I pointed it out and it caused a big scene.  He deleted the post replacing it with a jibe about how he did nothing because no one had a sense of humor.  Thread nearly died after that but it's still plugging on.

What do you guys think?  Should I have kept my mouth shut?  I think probably I should have.

Edit:  Said "the primary mission giver" when a better description would have been "one of two characters in command"
