A civil right is defined as such:
"civil right: right or rights belonging to a person by reason of citizenship including especially the fundamental freedoms and privileges guaranteed by the 13th and 14th amendments and subsequent acts of Congress including the right to legal and social and economic equality."
Underlined portion is emphasis added by me. The right to keep and bear arms is a fundamental freedom and privledge provided to people by reason of citizenship. So would it be something that would be considered a "civil right"?
