Books can be publicly scrutinized, facebook feed will only reach it’s targeted audience. I think a more apt comparison is pamphlets at a rally. And even a rally is absolutely scrutinized—or even stopped by the police—if they are found to distribute illegal, radicalizing, or dog whistling material.
In real life there’s a loophole to get around this kind of scrutiny: religion. It doesn’t matter which one really. But if it’s religious and you don’t discriminate against people in obvious ways, you have much wider latitude to say eyebrow-raising things in public.
Seems like that works online too, now that I mention it.
