As one of the receivers of said war, I don't really see it as any sort of derpy war from an IC point of view. I recognize that it's a frustrating war for you, both because you prefer to fight in larger ships while we are pretty exclusively a frigate combat corp and because you feel you were pressed into this position of appearing as the "new Jade". I can't really speak to the former, but I'm a little curious why you let yourself get put into the position of being the spokesperson for a position that you don't really care about.
As far as that position goes, and the war in general, I think it's all good. Speaking as a former Jericho Fraction director, I loved the crazy posthumanist screeds that Jade would post as justifications for our wars - which is realistically what they were: justifications. As a corporation, Jericho Fraction discovered that it was a huge pile of fun to fight scrappy wars while engaging in IC agitprop, so that's what we did. It polarized a lot of people with regard to JF, and it gave us a nice pool of both allies and enemies. If that's not something that sounds fun to you, though, then that's a good reason to avoid those sorts of posts in the future. I don't know. That's only something that you, yourself, can say.
From a strategic and tactical point of view, this has got to be a really tough war for you guys. Your stated goal is to remove us from the Minmatar war zone. The only way to do that is to make it so difficult for us to go about our daily business that we pack it in. However, we are frigate specialists, and frigates have an unprecedented ability to dictate the choice of engagement. If I were in your shoes, I would give some serious thought to whether or not that goal is feasible. I'm not saying it's not, but I am saying that it's tricky. We win, after all, by simply ignoring you and going about our business. JF found itself in your position many times. Sometimes we were able to achieve our stated goals anyways, but that always required unconventional thinking.
What happens if you can't win this war? That's also something that JF faced many times. Sometimes you have to simply admit "we didn't win this one" and move on. In a war like this with an existing agitprop campaign, you're going to have to eat some crow (as Natalcya says) if you drop the wardec. So what? Shrug it off and move on. Lots of people love underdogs. Hold a post-mortem for the war - what went right, what went wrong, what should you have done instead. Regroup, learn, get stronger, and come back to win your next war.
In any case, I don't think anyone of consequence views you as incompetent because of any of this. I certainly don't.
