Please read my theory. Will you answer in the positive and negative with cited explanations?

Your premise is correct in Theory. The problem is, the country is run by elected officials elected by the general populous. The general populous is not interested in maintaining the rights of all people. It is interested in maintaining their own rights. If this were not true, we would not have questions of gay marriage, nativities on the courthouse lawn, faith based initiatives, slavery, oppression, discrimination, etc. etc. etc.
