Allow me to complete a forum thought in more words.
Fascists are incompatible with any public forum, for it is their nature to disrupt and destroy. To a fascist concepts like "facts" and "morality" are malleable playthings through which he can achieve victory. His retelling of events distort to his benefit, his beliefs of morality always conveniently lacking. Any discussion within which a fascist is allowed to insert himself will either become consumed by his deluge of falsehoods and misinformation or allow its perception of reality to warp into one wherein fascism is the only rational answer.
To a fascist a discourse must always revolve around himself, around his beliefs, and his enemies must never be allowed off the defensive. If you are not constantly defending yourself from vapid accusations or correcting banal falsehoods then the fascist is not happy, because you are free to challenge his ideas with your own. This is why he feels he must assault the concept of truth, redefine it to his benefit and liking. He feels that his worldview is rational, and if you do not agree then he must corner you into a world where you cannot consider anything else.
It should surprise nobody that the benefits of the fascist's actions are rarely immediate, there are few who will ignore the call to prove his dishonesty, but he was never interested in the truth and will never concede to its existence. If the fascist cannot be presumed correct then he will simply filibuster the matter, pitting the patience of his privilege against the reality of others. At best deteriorating a space into a constant battleground of people fighting against his gaslighting, and at worst outlasting his opponents and finally being allowed to reign supreme over the narrative, even if nobody remains to hear it.
