<< You are absolutely deluded, if not stupid, if you think that a worldwide collection of software engineers who can't write operating systems or applications without security holes, can then turn around and suddenly write virtualization layers without security holes.

Allow me to start by saying that you are wrong about 'mainly about'. The argument starts with an insult, but insult is minimal and it moves directly into the technical details. But, note that how much you are wrong about the paragraph, because what you want to focus is the insult. You are so wrong about it you effectively invert the proportions of presence of technical data to insult..
