The problem being, "professional debaters" such as politicians generally do not want cool and rational debates - they want to push their narrative at all costs, even if it is wrong. _Rational_ debate is not good for them - it may expose that narrative is false.
They don't care whether it is true or not, the narrative is merely a tool for them - to gain popular support, to appear to be "the good guy, battling against evil forces". Your only hope is to support him, or else all is lost, disasters and genocides are practically assured.
Since they practice doing this literally for years or even decades, they are real masters. Ever heard about "controlling the narrative", i.e. _preventing_ debate from deviating from controlled track and into having intelligent discussions with rational arguments?
This often confuses and frustrates people who are new to "discussions" of this type. They are lost. They can't figure out who is right or wrong, whose "outrage", "indignation", "shock" has any real substance or it is just theatrics.
It seems to be contagious. Non-politicians also somehow get drawn into this behavioral pattern. Maybe subconsciously, we are all "a bit politicians"?
