There is a saying that as soon as a person brings the Nazis into an argument to prove a point the point and argument is lost
Look up Godwins Law, then re ask your question. (extract below)
Godwin's law is not really about Nazis, .... The actual insult could be any slur or imputation that demonizes the target - depending on the forum, the triggers words could be 'communist', 'capitalist', 'pedophile', 'Suethor', or anything else meant solely to evoke rage and disgust from the other posters.
The point of the law is that the more protracted and bitter the argument, the more likely it is that someone will resort to name-calling or some other form of ad hominem attack. The corellary is that this usually causes a chain reaction as everyone begins to reply in kind, and any intelligent debate still remaining will get pushed aside by increasingly strident and vicious mudslinging.
The real lesson to be taken from the law is that it is senseless to continue a stalemated argument between two irreconcilable positions unless you can bring something new to the discussion.
