Because the use of 'false facts' to support an otherwise sound argument really pisses the tits off me, I was compelled to write this post.

Concerning the US Constitution, Mike wrote the following:
"Any of the amendments can be removed at any time providing they get Congressional approval to do so. Congress could take away every single one of the items on the Bill of Rights if a majority vote decided to. "

It isn't quite that easy to change the Constitution. There are two ways to do this:
First Way: two-thirds of the entire US Congress (that is, the House and the Senate) must approve any amendment (and REMOVING an amendment is also an amendment--an example is the amendment that repealed the amendment making alcohol illegal in the US). Then, the amendment must be approved by three-fourths of the states' legislatures. (or, I believe, the number of states which must approve is 34)
Second Way: This has never been done, but it would require that two-thirds of the states' legislatures petition the Federal Congress to call a convention to discuss and write possible amendments. These too, would also have to subsequently be approved by three-quarters of the states.
I will say a prayer tonight in which I will fervently thank God that the process of amending the US Constitution is not nearly as easy as Mike wrote.
