I feel like you already have the mindset we appreciate. You already said you don't post when it's relevant or things you don't deal with, but when you have stuff to say that you have experience with. My problem is when people hijack a post and start long arguments about things not about the original poster's comment, like coming in with "oh, this is all just male bigotry" when it's been clearly said before it's kinda guys just ranting.
As long as everyone it being thoughtful and on-track, ftm, mtf, pre-op, non-op, post, doesn't matter to me.
