There are many laws out there I find unconstitutional, but I'm not an absolutist. Absolutism is not practical in a society as large and diverse as ours.

I believe felons should not be allowed to possess a firearm.

They have shown a willingness to break one or more laws and imprisonment seldom works as rehabilitation.

Should there be a path where they could eventually have that right restored? Sure- I have no idea what it would be because I don't really care.
