Again, you are arguing to the opposite result of what an in depth analysis of the current world situation would lead to.
First of all I am not going to engage a debate in a dishonest way. Call it my upbringing, my character or whatever you like but if I do engage in a discussion with someone, like I am with you now, I do it with the premise that I don’t hold the truth in my hands and that I can always be persuaded to change my mind if presented with a correct reasoning and with truthful data. This alone does not allow to follow your magnificent suggestion to use dirty debate tactics and false information to fight a wave of bullshit I would be subjected to should I entertain an exchange with a fascist, a nazi or a communist.
Secondly, it is impossible to fight in a logical way an argument which has been implanted in people minds through emotions. The only thing which can counter this seedling is an even stronger emotion and, as Germany has reached us with its re-education campaign following WWII, shun and shame are two perfectly fine instruments in this effort.
Thirdly, there is not an hypothetical in my phrasing (if they were to come to power) because they ARE already in power in states like Texas, Florida and other nations around the world and we can clearly see that, in order to preserve this democratically obtained power, they are dismantling the same democracy which gave them this power in the first place.
Lastly, your free use of terms such as “some”, “someone”, “a few” does present the issue as if it touched to a small number of people. May I remind you that 74 millions people voted for Donald Trump in the 2020 elections? Are they all fascists or nazis? Impossible, but still they are all ready to give a fascist the keys to the white house for a second term, so they are all part of the problem.
A problem which, I reiterate, cannot be solved by simply sitting down and calmly discussing with someone asking for the eradication of a minority for the betterment of his own life.
