I wonder if half of bitcoiners realize that arguments on reddit and other places caused by someone's inaccurate depictions of bitcoin aren't due to actual ignorance, but are in fact intentionally inaccurate to draw out the emotional and overly defensive crazies for comedic value. Bitcoin or not, crazy is never good.
I remember that, too, from the early internet. Many mass media tried to trivialize and belittle the internet, its impact on society, and its users. And when the dotnet bubble burst it was all over, the internet was dead, we'd go back to the old ways. That mostly went away as years passed
Good ideas won't go away when people are laughing at them. But there is an initial hostility toward new technologies, what Michio Kaku calls "The caveman principle": If it wouldn't appeal to our early ancestors, it won't appeal to random people now.
Anyway, the earlier advocated were very different from the latter ones. Take for example another idea that was severely belittled and underestimated in the beginning: free software. Though he was great at pitching the idea to software developers and idealists back in the day, most news outlets are not going to invite Richard Stallman to an interview about the subject. He's just too extreme.
As a latter-day advocate you need someone that is likable in the eyes of the masses, doesn't make them think too much, doesn't say anything too politically incorrect (or idealistic), wears a suit and tie and makes great promises, tells you why *thing* will make your friends and family love you more, makes your skin look younger, improve the taste of your food and improve your sex life. Only that, and generational shifts, will conquer the caveman principle.
