Lawmakers (the People) are the ones who make the decision on the appropriate use of a gun. They have decided that pointing a gun at an intruder is appropriate, I agree. These are state matters and states do differ.
If you pull a gun to rob your fellow citizen - that is not going to be acceptable to me or many others.
If you use it to rob a store or a bank or a church - that is not going to be acceptable.
If you kidnap someone at gunpoint - guess what?
This is not difficult.
As it stands the loss of rights by felons is spelled out in the law. Most citizens have no problem with it. Extra non-judicial or unconstitutional punishment should not be allowed.
When you get the law you are concerned about properly identified I could discuss it. If it is not constitutional that will be before the courts before too long and it will be overturned.
Like the Affordable Care Act was overturned?
The "Law" is actually much worse than the little bit I shared; to wit:
(d) It shall be unlawful for any person to sell or otherwise dispose of any firearm or ammunition to any person knowing or having reasonable cause to believe that such person -
(1) is under indictment for, or has been convicted in any court of, a crime punishable by imprisonment for a term exceeding one year
(2) is a fugitive from justice;
(3) is an unlawful user of or addicted to any controlled substance (as defined in section 102 of the Controlled Substances Act (21 U.S.C. 802));
(4) has been adjudicated as a mental defective or has been committed to any mental institution;
[...]
#1 is plainly contrary to the Fifth Amendment which states that liberties cannot be denied w/o due process of law: mere indictment does not qualify.
#3 is plainly contraconstitutional, the federal government is not Constitutionally allowed to regulate substances (see the 18th and 20th amendments); moreover as it references some other regulation, that regulation can be changed to disastrous consequence: making water a 'controlled substance', for Environmental reasons, would be an example.
#4 is particularly dangerous, given that there is one prominent instance where, in order to silence opposition, those opposing the government were labeled as mentally defective by the government: Russia.
So, please explain to me how anyone who loves Justice can love this 'law'*.
* - I maintain that it, being contrary to the Constitution, is not law.
