so we're going to be ok with a majority overriding the constitution because it makes them feel safer?
They are not overriding the Constitution. States have that authority under the Constitution. The 2nd did not restrict state action until 2010.
See McDonald v. Chicago. Justices Scalia and Alito agreed the 14th Amendment incorporated the 2nd to apply to the states.
