The thing is, you're not an INFJ, you haven't taken the time to truly understand where we're coming from, yet insist that you know what is best for us to do. Not only that, this thread wasn't started as a "How Can I As An INFJ Get Along Better With ENFPs". It was started as a window into our way of thinking to see if we can better untangle why/when misunderstandings occur or what we as INFJs all identify with and what we've done/are doing about it. I am open to people's advice, but only if I have solicited it and feel that they are qualified to give it to me. You have chosen to come to an INFJ discussion thread. Even though you are welcome to contribute, you are a guest, just as I would be on a discussion thread about why ENFPs think as they do.
Unless you go back and address the concerns we have as valid or we figure out where the misunderstanding happens, you will find that INFJs will continue to resist you or the points you are making steadfastly, even if there is something useful in them. By ignoring those points of contention or dismissing them as invalid (as you did in the Doorslam thread as well), you are ensuring that you will not be heard and will further contribute to the negative impression that INFJs may already have. Every little bit of difference will grate against us and annoy, where it would not normally in nearly the same way. When you go back and sort those things out, you will find that INFJs are surprisingly more receptive, polite and will overlook misunderstandings much more easily.
No matter what your opinion is of this phenomenon, it's how we work and I doubt that you will see everyone switch their way of perceiving things or change completely just because you think it's a better way. You are more than welcome to bring up, "But what about x?", but ignoring the elephant in the room will ensure extreme bluntness that is uncharacteristic of us. The previous examples of non-private directness, outright disagreement without looking for common ground or specific examples of what was wrong are usually very good warning signals from an INFJ. If pushed further, they will no longer filter what they are thinking and will not take the wide audience involved into account in the way they would if you noticed those signals and backed off in your approach.
