"Fortunately" (and I don't mean to encourage it), the abrasive people in the crypto community are like that when they tend to be right - and don't want "newbies" to do stupid dangerous mistakes, so their tone comes out a little aggressive by default. But yeah, it could be improved. The community should work together on solving issues the right way.
Fortunately or unfortunately, there are also a reasonable number of abrasive people who tend not to be right, so I'm not sure it's a good marker either way. There's a whole rock-star persona around people who make consulting careers out of trying to position themselves as security badasses, and not all of them are.
