ozonitabetai, I don't know if I can say that your sentence is grammatically incorrect, but I can say that I have a real tough time figuring out what it is supposed to be saying^^: "Except for what happened yesterday, how are (you, we...) going home today?" is how it reads to me. So, I'd have to say that for my two yen, it's probably not an ideal application of the grammar point.
It is just an example in the use of this grammar entry. Relax and get a life.
Can we get some non-religious examples that can be used for normal communication? Should this really be a place to advertise religions?
