They simply need to know exactly who they may have as their newest client and the questions are perfectly normal for them to ask. I never found it as a sign of passive-aggressiveness when I had to go through the usual rounds of questions, because I knew that they wanted to get to know me, and I don't think that answering once on a piece of paper to be forwarded to hundreds of prospective therapists would be considered useful. They are there to help, usually.

Yeah, there are some real bad therapists, but there can also be good ones. Just remember that these prescribed questions are there for a reason and they aren't trying to attack you.
