To Whom It May Concern,
I am writing regarding the Swift Boat Veterans for Truth tv ad. I am appalled that you are refusing to air the ad, by decorated war heroes. It shows the leftist slant in the media is true. I am sure you had plenty of coverage on the Fahrenheit 911 crockumentary, even though it was based on lies, deceits, and distortions of the truth. I can not believe in this day of free speech and equal rights for all, that you would censure decorated war heroes. It is a sad day for this nation when those who put their lives on the line to protect this nation and ensure free speech and equal rights for all, are being drowned out by censorship. You should be ashamed! I am asking that you give the Swift Boat Vets the same treatment that you give John Kerry and every other political organization. Please do not take away the rights of those who fought to defend those very rights! Please allow their voices to be heard. Please do not refuse to air the ad. Thank you for your time.
Sincerely,
Todd
Not to sound too nitpicky, but the word is "censor", not "censure". "Censure" is the slap-on-the-hand cRATS wanted to give to Clinton. If you're trying to make an argument, it is a good idea to proofread.
