Completely agree. I wasn't interested in having a girlfriend or getting married right away, and I got that question almost constantly. The other one that makes me angry to hear is questioning about having kids. Can you imagine how heartwrenching that question could be if you had just lost a baby? I've seen a situation where someone wouldn't let that rest, and the person they were asking had that exact thing happen.
The other questions I don't have as strong of a reaction to because they wouldn't personally bother me, but I certainly wouldn't be asking them myself!
