Usually, if you want enrich yourself or your friends, you’d want to create a climate favorable to economic growth and skim little off the top of that using the usual corruption methods. You don’t want to start a multitude of trade or literal wars that threaten the global economy.
If it wasn’t for Trump being the cause of this, you’d almost think this collapse is intentional…
This can easily backfire, though. The fascist will rarely start the debate by glorifying the Third Reich. Instead, he will start off by lamenting the state of the working class, or complain about foreign policy, and only progressively reveal his true agenda. Showing contempt for him at this stage could be interpreted as contempt for these issues.
What the fascist attempts to do in these debates is to acquire legitimacy, since their political position sits outside the overton window. Using logical fallacies against him is to basically hand him that legitimacy for free by making him appear “reasonable”. The easiest solution to all this is not to debate them at all.
