Man up and prove your accusation.
I already have. You refusing to doxx yourself is the proof that you're full of shit.
What are you so afraid of by coming clean with your actual name? Are you afraid that you'll be exposed as an exaggerator? Are you afraid that somehow, retribution will be taken against you for being a Nazi? I don't understand what you're so afraid of? You made your personal fortune central to your character and central to your argument. Now, you're refusing to support it in a way you know is unquestionably verifiable.
I think you're just a poseur who wants other people to think you're more important and successful than you actually are. If you've been in this game long enough, you start to see the same patterns with the same people over and over.
