Pros and Cons to Standardized Testing

I found this website, http://standardizedtests.procon.org/, which gives really interesting statistics on different views of standardizing testing. I disagree with a lot of the arguments given in the "pros" section on the website. For example, it says that these standardized testing are non-biased and most teachers do not feel like they have had to compromise their teaching practices for the tests.  I think these two arguments are the complete opposite of what I talk about in this class and others. Take a look at the article, I think you'll find a lot of them amusing.  What it frustrating is that we consistently talk about the negatives of the standardized testing, but how come they're still around? Don't you think there has to be some kind of good thing that comes out of it that is keeping it around? If not, why are we still making our children take these tests?
