Do you think that it's rude? It seems sensible to me.
It seems that people interpret such actions as hostile. And people who say things like that probably are hostile. However, I don't think the likelihood of the person being hostile is high enough such that you should conclude that they actually are. I think that the likelihood is low enough such that the courteous thing to do is investigate further as why they're saying that.
And if they're well intentioned - ie. they want both parties to find someone that they're compatible and happy with, and are just trying to do a good job of that - then I think the mature thing to do is to respect it.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
