You're wrong about this. If you think that the best ideas naturally win out you're either ignorant (think of how fast bad ideas can spread), or purposefully pushing this "both sides"/horseshoe theory/false equivalence to further impede those who are actually trying to stop fascism.
The "deplatformers" you're referencing here wield entirely different magnitudes of power:
Erdogan: literally an authoritarian dictator
Carlos Maza: journalist who brought attention to the fact that hateful speech has real violent effects on people (it's important that Crowder's videos were only demonetized, not removed, or his channel suspended, and that this action was taken by Youtube).
Antifa: organization with no leadership structure, composed of citizens who are dedicated to preventing fascism from spreading, using means that are historically proven to work.
