Whenever possible, try to introduce new ideas that haven't been hashed out over and over.
But sometime's this happens.
Even though the idea is new (or you just think it's new) sometimes someone else thinks it's the same thing.
When this happens....You move on.
Sometimes the only way to win, is not to play the game.
Many of the people here who talk like that have been here so long they are mods or have at least some mod powers.
Chances are, they lock the thread right after.
Don't PM them on it, or they'll threaten you.

The argument is over. Find something more important to do than being right.
If you are daring, call them on it. Politely
ask for links to old arguments. You might learn something new. The worst thing that can happen, is you'll be wrong on a minor point of fanboy trivia about the magical laser on the "Deathstar". I know I can live with that.
Move on. Write some original fiction. Toss out another new idea on another part of the forum instead. Comment on the news. Realize you aren't getting paid to debate. Live Happy.
