Lol. That's a poorly worded excuse for a come back that doesn't make an actual point and puts words in my mouth I never said. Additionally it adds meaning to the words I did say that don't make any sense.
Further, since your computer is in fact fairly insecure (look up how easy it is to just completely bypass windows and install Linux) I wouldn't be opening myself up to further arguments in this vein if I were you. Emails get hacked all the time. It's literally a scammers paradise. Know one of the things that prevents spear phishing and other attacks? A physical security key. Or multi factor authentication. What are you even on.
