And I'm suggesting to you that the entire context of the situation gave no chance of that. The rebels had arrested and silenced the Communists in their area, and they were led by a fascist. Again, as I said, had this been at peacetime in a fully solidified USSR, where the Communists held a large enough power difference to enable such a trial or hearing, then that would be a different manner. Referring to Konstadt specifically, of course. Additionally, at Kronstadt, the rebels stepped down and arrested the leaders of the revolt, and were fine.
The fact is, the Anarchists had their own ideals they felt valuable enough to fight Communists to the death over. Either you're defanging and making useless the Anarchists as useless smol beans, or you're misrepresenting them as strong yet entirely in agreement with the Communists, neither of which is true. The reality of the situation was Civil War, where multiple sides fought for their own interests and ideals, the Anarchists were in no way a neutral faction.
The Kronstadt rebels arrested the communists, because false rumors were spread about Communists killing workers and strike leaders. The Bolsheviks were led by Lenin, though Trotsky was in charge of Kronstadt. The rebellion was suppressed as it began, violently, until the rebels turned on the fascists and rejoined the Communists.
You aren't doing any material analysis, just vibes and idealism. You ignore all context.
