I don't think that's a good example. The science crank has repeatable and falsifiable evidence against their opinion. For political opinions, well, remember that MLK was widely disliked at the time of his death (https://www.smithsonianmag.com/history/why-martin-luther-king-had-75-percent-disapproval-rating-year-he-died-180968664/ https://www.smithsonianmag.com/history/why-martin-luther-kin...). Should his opinions have been kept out of the press? Believe me, after the last few years, I'm all for keeping cranks out of power but not at the cost of creating a mechanism that can be used to suppress grassroots movements, regardless of stripe. That's dangerous; "what goes around, comes around" eventually.
