You could wipe every reactionary television station, radio station, magazine, social media, and newspaper off the face of the earth, but capitalism's internal contradictions would make their resurgence inevitable.

So long as wages are suppressed, social safety nets withered, wealth inequality balloons, education decays, retirement age grows, and healthcare becomes unattainable, the backside into fascism is inevitable.

How do you think fascism took hold in Germany, and how was it mitigated?

Your analysis falls into the same trap as other liberal analysis - that our means of changing our politics is a function of "changing people's minds" in "the marketplace of ideas". Liberal analysis champions the notion that "ideas" are what turn the wheels of history. In reality, it was Soviet T34s blasting Nazis into mist that mitigated German fascism - not some completely unachievable and unpragmatic scheme to break into retirement homes across the country and put parental controls on grandpa's favorite flavor of right wing pundit TV.
