Sharing for discussion. Even if he's overselling the predominate online bitcoin culture as The Bitcoin Culture, we did something to leave a bad taste in his mouth. Bitcoin's online culture is rather prickly but would bitcoin be the same without it?
Being online appears to cause an over-exaggeration of opinion as if we might anchor counterparties to something other than their own opinion. We do it - probably - to create contrast between ideas that might not be visible in a fast moving algorithmic feed.
Something that I've found useful is considering if an opinion is not as stated, especially when unsupported with facts, and instead an attempt to move my perhaps wrong opinion. Some people are wrong and some people are mean, but some people are wrong and mean to lazily make a point.
The toxicity in bitcoin isn't its culture but the author isn't alone in thinking it is. As far as I can tell, the toxicity is an attempt to counterbalance something else and while some people have become career-counter-balancers, they're just one of many forces defining bitcoin.
I expect the toxic element to leave bitcoin once its position is more secure. In the meantime I'm not sure it survives without toxicity and people challenging the toxicity.
