That is not even close to being a summary of the story. Sorry. It's not just about mentioning pizza in an email. Your comment was once again completely pointless, I have already told you that what you are doing is only virtue signalling. You just call other people dumb and then link to people agreeing with you with 0 information or content.
Do not accuse people on HN of "virtue signaling". That's simply a way of saying that someone is lying, or commenting in bad faith, not because they believe what they're saying but because they're trying to curry favor with some other group of people. It's semantically indistinguishable from accusing someone of "shilling", and that's one of a very few arguments that's specifically forbidden on HN:
There's also no way to make such an argument civilly, and civility is a basic requirement for commenting on HN.
Making arguments on HN is trickier than making them on Reddit, and you may find it's not worth the energy. There's nothing wrong with keeping your discussions there.
