I really don't agree with people's comparisons of WWE with the gun references and TNA's ludicrous use of the knife with Samoa Joe. Its not the same thing at all and WWE's use of the gun is not by any means worse then TNA's use of the knife. Firstly, lets take the example of Austin and the fake gun on Vince McMahon, shall we? It wasn't real. It was shown to be a completely fake gun and therefore any implications were countered and it was a freaking joke gun! He wasn't trying to seriously kill McMahon and anyone who tries to argue that is an idiot because all seriousness was thrown out the window when it was turned into a gag. That didn't leave people watching, especially children, with any impressions at all except that it was a gag at the expense of a heel. They went out of their way to make light of the situation and yes it pushed boundaries and pushed the envelope, but the ending stopped it from being what the criticism of Joe and his knife has become.
Secondly, let's take the Pillman/Austin example. Pillman was in his own house and was using the gun to defend himself, as Austin was portrayed as the bad guy who was out of control. The commentators weren't behind Austin and urging him on, claiming he was doing the right thing and was justified by invading Pillman's house and attacking him. Nothing was glorified about the situation which is completely different from Joe's example. Not to mention that the WWE was highly criticized for that segment and its viewed as a bad judgment and likely they wouldn't have done it again knowing what they do now. Its seen as going too far..
In the example of Joe and his knife. Not only does TNA have a commentator praising Joe and justifying his actions as if its okay to go to that extreme to gain revenge, promoting such actions as justice basically.. but Joe's the Face. Joe's suppose to be the good guy and he's resorting to putting a knife to the throat of the heel and threatening to take his life, no gags.. no jokes.. no light side of it.. which promotes people to get behind Joe's actions because he's the good guy. Not only that but Joe and TNA are promoting this nation of violence, and what does this nation of violence stand for? A guy scorned is out for revenge and instead of being able to go down and do it in a normal face way, by his own ability and making the heels fear and be threatened by him because of who he is and whats he's capable of on his own.. the heel is afraid and threatened because the guys got a knife and is threatening to use it. It goes beyond common sense. It goes beyond any logic in terms of booking in wrestling, and once again its likely an example of Russo's influence destroying the business. Like he did by making championships nothing but props. This isn't the same as some television show thats clearly fiction, this is wrestling and people ARE influenced by what they see wrestlers do and don't view the product the same way people do normal television shows. Thats been proven by children of all ages pretending to be wrestlers doing their moves, acting and speaking like them, and so on and so on. People who use the argument of other television shows really aren't seeing the clear holes in such an argument.
This is going to be viewed down the road as another moment in wrestling history where people look back and criticize it for being stupid and a bad idea. Its not going to make Samoa Joe cool, its not going to have a favorable effect on the product, and in the end it makes Joe's character look weak. It contradicts previous Joe characters as he'd never have resorted to using a knife before, he would've come down and just kicked people's asses because he could. TNA's booking and writing sucks, plain and simple.
