Would you please make your substantive points less aggressively? I appreciate that you know a great deal about this topic and we all probably have a lot to learn from you. Nonetheless you crossed the line here, and not only here—repeatedly mocking someone for their username, for example, is a cheap shot. You undermine your own arguments when you do things like this, in addition to poisoning the culture that we're trying so hard to prevent from becoming outright toxic.
