Instead of calling him out over his "obsession," please try to respond to his argument. Is he wrong? Is he making incorrect assertions? I am genuinely curious. I don't know a lot about cryptography, blockchains, bitcoins, etc. I try to take everything with a grain of salt, but seeing two knowledgeable people civilly discussing the merits of these things would be interesting. Calling someone out for "being obsessed" isn't.

To use your angular analogy, if someone went around criticizing angular everywhere, I'd like to see a discussion between that person and a pro-angular guy. Because I guarantee there are smart people and good points to be made on both sides of that argument.
