>Comparing it to Stalinism is silly, and surely disrespects

No, making a comparison of abstract forms of government is not in any way disrespectful to people who lived under a regime. It can only be construed as disrespectful if you are looking for an emotional tangent to distract people reading from the argument at hand (which, incidentally, indicates that you know your argument is bad!)
