Asking others for input on relationships, including the therapist relationship, is par for the course for much of humanity. I can understand you feeling impatient with it, but not sure your rant will convert many, haha.
Keep in mind that folks don't necessarily forum-members' advice *instead* of the other party's, but often before taking it up directly. In the meantime, they for reassurance, another set of eyes, perspective, etc., all things that can help them address the primary issue better.
Although I typically like to keep relationship issues within the relationship, I understand a one on one relationship doesn't always feel safe and the individual doesn't feel clear enough to always immediately engage directly, especially when dealing with folks suffering from PTSD. I know that's been true for me at times, and I've really appreciated all the support I've gotten here and elsewhere, including even the dissenting and less common opinions, because they help me chip away at the interference in my head and heart until I get clear on what's most important for moving forward and what I really need to ask for or get from my therapist.
It is very easy to say "go ask the person" but clearly, very frightening, painful and confusing to do that for some of us in some situations.
Not to say internet advice is a substitute for expert advice or that anyone here is a mindreader, but I think most folks understand that.
Your rant was a good reminder for me, because I am very direct and do like to go to the source. So I often advise others to do the same, but try to be understanding about why that's difficult.
I was reminded of even my own struggles with this and that we're all at different places, needing different things.
