If you are open minded and jump in you’re in 

 Batman and joker, they're both bitcoiners. 

 It's pointless wankery, no one can ever be pure enough.  Instead we should focus on how to trick as many people as possible into using bitcoin atleast once.  The ETF is good, but I'm invisioning an addictive phone game that uses bitcoin as its in-game token. 

 @THNDR has a few of these. 😉 

 If “puritan” means “takes a stand to dogmatically define what it means to be a Bitcoiner,” is that materially different from your post? Aren’t you also drawing a line, albeit in a different place? Do you understand the word “puritan” differently?

I mean, the real Puritans were so committed to their beliefs that they willing to leave a land where they were being persecuted (alongside everything familiar and comfortable)  to move to America, where they managed to build it to the point that it outsmarted, defeated, and replaced the most powerful empire on earth at the time. There are way worse things for compare Bitcoiners with.
