2 and 3 are basically the same.
And I would rephrase 4: "You are not honest about your intentions and instead of discussing things you only want to prove that you are right."
Furthermore I'd like to add that "copy-pasting" info or dumping links is not a discussion. If you post a link you have to give your take on it. Explain why it is that you feel that this particular link is correct. Besides, in discussion it's vital that you read all of the arguments of the other person. It doesn't work when you just let the other person talk, but you don't listen to him. That's also why copy-pasting should be omitted as much as possible, as well as link dumping. We're here to discuss with eachother, not to let several sites argue with eachother indirectly.
