No one can tell you how to run your faction, just do what you will. As long as you and your faction members are happy, there's no reason to listen to anyone else.
As Yas mentioned, if you take certain actions in the middle of a very public event, you concede that those actions are open to both praise and condemnation. In the more recent case, there were plenty of reasons to come down on your actions, but thus is the nature of RP. You shouldn't immediately reel back onto the defensive and become exasperated over those who choose to call you on things. If you've explained them as they're true to you, then that's all you can do (not intentionally rhythmic).
I really don't know why anyone would get mad at Ronin for choosing to farm or not PvP. PvP is not the ultimate goal of the game. This is defined by the individual(s), as per the wonderful tool of autonomy. There is the paradox of not PvP'ing on a hostile server, but again, what you do is entirely up to you.
I've previously stated my strong, in-character concerns with Ronin, and they have no place here. However, it goes without saying that my concerns shouldn't become yours if you're just going about your business as you see fit.
If I were you, I'd ask for this thread to be deleted, Ian. There's no reason whatsoever to search amongst the opinions of others for the manner in which to lead your faction.
