Partisanship, including centrist, not only stops your brain from being able to identify the lies, incongruencies, and bad behaviour of your leaders but causes your brain to actually reward you for doing the mental gymnastics required to fail in this way ( cit.  https://pubmed.ncbi.nlm.nih.gov/17069484/ ).
When you are unable to see any merit in the thoughts and statements of those in opposition to your leader, when your partisanship stops you from recognising the serious problems in the thoughts or statements of your leader, when you oppose ideas and statements that you used to support because they came from the opposition... you are no longer participating in politics or debate; you are participating in a cult - and that applies to leftists, centrists, liberals, libertarians, right-wing, conservatives... EVERYONE
