This is a semantic disagreement. Democracy can be a system of government or a method of controlling and staffing government. As for a form of government, I have yet to meet anyone who considers "democracy" a form of government where the entire electorate votes on every issue of governance without any limit on government power, i.e. protection of individual rights. It is quite widely considered a form of government wherein government is limited constitutionally (individual rights recognized) and position of power chosen democratically.
