I could not write a better, clearer, more moving post, so I am linking you to my cyber-friend, Melissa's blog to read what she has written and compiled.
In my opinion, it is of the UTMOST IMPORTANCE that you read her post.
PLEASE, PLEASE, PLEASE, read this.
It really is a matter of life and death.
(p.s. I promise to stop SHOUTING at you when the issues do not affect the fate of our nation).
