I Personally love the encouragement to "go play diplomacy". Sends a strong message of support and unity. Dirty, your sensibilites are too sensitive if you are offended. I think you must have been on the rag last night 
I will say this:
I've noticed a couple of things since playing my first few games of Diplomacy starting 2 nights ago, don't know if they are trends yet, but nonetheless, here goes:
With the release of Trinity, I have noticed a lot of new players with little or no previous experience in Entrench or Vanilla coming on lately. These players in general are not biased or otherwise close minded like so many "experts" here, and they are eager to embrace the game. Also, these new players seem to be increasing, and as long as we embrace them in turn, they will provide a much needed influx of new blood for the community as a whole, and will be measured by a "head count" of growth numbers, instead of a "body count" of those lost to division among the expansions. I feel the argument that "sins is dying", or that, "I just want to play it safe in Entrenchment because we can't risk dividing the player base" is ridiculous. The growing number of new players, and the willingness of most veteran players to migrate/advance to Diplomacy is evidence of that.
Being that I've only played like 3 or 4 multiplayer games, I am not one of the experts, but I can say that so far, compared to Entrenchment, Diplomcacy offers substantial improvements overall. The pacts alone are a tremendous vehicle for implementing game strategies. The course of events leading up to and following the diplomatic aspects lend an entirely new flavor to the "business as usual" tactics of multiplayer games. The increased speed and relative dynamics of the trade pacts it brings to the game surpass any single benefit compared to Entrenchment. Because of this, you not only can and should perform true to your initial role (depending on random map placement) as a front line, or support effort, but you have the opportunity to expand and solidify your pacts over the course of the game.
The bugs and fixes will come, but for now Diplomacy is now far and away superior to entrenchment. It's what Sins could have been all along.
And all you fellas that just want to argue for the sake of arguing are just being iconoclast in a devils advocate sort of way; Kharma, I'm afraid, would argue with a fencepost, doesn't matter the issue. Quar has a needle-saturated voodoo doll of KL3MZ on his mantle, and like those that are resistant to change and stuck in their ways, will find something to complain about regardless. I think attitude is everything, and when I play, I want to maximize my enjoyment. Diplomacy has brought a great deal of excitement to the table towards that enjoyment.
Try it, you'll like it!
