Declaring that everyone that the Social Security Administration thinks needs help to deal with their agency's financial requirements is too mentally defective to own a firearm with no notice, no administrative hearing and no judicial review strikes me as being arrogant and also in violation of the 2nd Amendment to the US Constitution.  

I approve of HJ Res 40.  So does the ACLU and dozens of Mental Rights organizations.

"We oppose this rule because it advances and reinforces the harmful stereotype that people with mental disabilities, a vast and diverse group of citizens, are violent. There is no data to support a connection between the need for a representative payee to manage one’s Social Security disability benefits and a propensity toward gun violence."

"The rule includes no meaningful due process protections prior to the SSA’s transmittal of names to the NICS database."

You are free to stigamatize of course.
