If, as you say, this is entirely an educational project (which I am willing to accept is likely), then all arguments put forth by the pro-dairy crowd are irrelevant, and it is a very wasteful way of educating a small group of students. It is not intended to promote dairy goods or benefit anyone in the dairy business.I doubt that this was in any way precipitated by the dairy industry of Missouri and was likely concocted completely by the educator and the senators office. The idea that every moment of every congressional session can be spent on the most serious of matters is unobtainable. Accept that some time will be wasted.
By the way a large amount of time in our legislature is spent on mundane issues such as accepting the names of post offices. This is also the same legislature spending time debating whether Missouri should use A.D. and B.C. or C.E. and B.C.E. as the official time denotations.
As for the waste of time, I agree they waste a lot of time, thus a lot of my money. This does not mean I have to like it, and I damned sure have the right to speak out against it where I see it happening. I also agree that the other examples you gave are a complete waste of our govt's time, and are as illegitimate as the official dessert is.
The only solution... make examples by kicking out of office those politicians who waste their time and our money on this sort of B.S.
