No, it is not. Read this section of the 5th Amendment again:
nor be deprived of life, liberty, or property, without due process of law
I think 99 percent of the posters here agree that firearms ownership is a key bulwhark of liberty. And I see no exemption in the 5th for situations where it's inconvenient for the feds to issue a mandate without millions of hearings to provide due process to those it wishes to deprive of 2nd Amendment rights.
If we allow the feds to deny the right to own firearms without due process, then every other right can be denied without due process. It's that simple. There should be a process with a hearing to deny gun ownership and an appeals process. Otherwise, due process is a joke.
Prosecutions are very local events. Federal government add-ons to local sentences gives the country consistency from jurisdiction to jurisdiction.... The delicate balance is in how much.
Uh, last I checked, there was nothing delicate about it, just the application of the federal hammer-fist to the 2nd Amendment. I don't entirely disagree with the end, but I disagree with the means.
The due process is the felony conviction. The one that limits their "Life liberty and pursuit of happiness" by putting them in prison. Other pursuits are also limited in that process, including their right to bear arms, and their right to participate in government.
