I shudder to think what God has in store for them after having used it as a urinal

At the risk of being the skunk at the orphan's picnic allow me to says this:
The money changers, merchants, etc. in the Temple courtyard were there for the sake of those who came to worship at the Temple. The money changers would --like modern international bankers-- change the money of the pilgram/traveler to the local, useable currency; not only for non-religious uses (food,drink, lodging) but for donation(s) to the Temple itself.
The men selling animals were also there for the benefit of the pilgram, who would buy the animal-- chiefly birds, in some cases sheep, and every great once and awhile cattle would find a buyer (but not too often as cattle was extremely expensive. Like donating a brand new Lexus to your church or temple) to offer for sacrific in/to the Temple.
I am not saying that Christ had no reason to be angry. I only bring this up to show that the courtyard of the Temple was not some sort of jumbo flea market.
Also intresting to note is that fact that the Roman SPs (for want of a better term) were not called in. Giving thought that actions of Christ "upset" only a few of the Temple merchants. A symbolic gesture, as it were...and there is nothing wrong with that. After all, one doesn't have to drink the whole glass to tell if the milk's gone sour.
