Please refrain from attempting to conflate your irrational beliefs with substantiated fact.  I have the same natural right of self defense on the 16th Street Mall as I do within the walls of my own home.  Now, I might not have a right to display my discontent with the government by standing in front of the State Capitol with the stock of an AR-15 pressed against my cheek and the barrel pointed at the governor's office window (as was written in the SCOTUS decision pertaining to bearing arms in any manner for any purpose not being protected actions under the Constitution) but that is quite a different matter than the Constitution not protecting my right to have that AR-15 in my car or at my place of business.
