It is weird and its not weird. Many people know him personally and my guess is that he just likes trolling and being toxic online. I have been around people like NVK for many years. Its not uncommon in smart technical people to behave like this. Its counter productive though. I expect that NVK is a nice guy if you get to know him. Bitcoin has a taste for toxic behavior online especially. It shouldn't be surprising. I don't mind people being opinionated and sharing that but I don't think it is helpful when we point the guns at our allies.
