The national debate for gun control has triggered outraged escalating to terrorizing heights.
A threatening letter addressed to President Barack Obama is believed to be laced with the deadly poison ricin, which has no known antidote.
The letter closely resembles two letters sent to New York City Mayor Michael Bloomberg and his pro-gun control advocacy group.
All three anonymous letters contained the same sinister message from an apparent gun advocate. Part of it reads:
"You will have to kill me and my family before you get my guns. Anyone wants to come to my house will be shot in the face."
"Just because somebody associated with their issues does something really stupid or criminal doesn't mean their not any legitimacy to the overall issue," said John Harris, Director of the Tennessee Firearms Association.
The Tennessee Firearms Association is a not-for-profit corporation dedicated to defending the right to keep and bear firearms.
Harris said this latest threat to gun control advocates has no effect on the gun debate issue, especially here in Tennessee.
He stresses their are proper ways to push for political causes, but sending a deadly substance through the mail with the sole purpose of bringing harm to people is not the answer.
"The right way to do it is through educating and building political alliances. Those kind of letters and attempts to poison people are futile. They're just stupid," said Harris.
The FBI is doing forensic testing looking for any clues that might identify who sent them.
