If you start from an unproven assertion ('all government spending is waste'), you can believe whatever you want. Things like, "Hey, I'm not being an out-for-myself bastard who's reneging on his obligations to society by being a tax cheat, I'm John Galt! I'm a good guy!".

You might believe long-term capital gains tax rates are too low. But if you're implying this man is a tax cheat who's reneging on his obligations to society, that's just slander. As far as I can tell he followed the law, paid his taxes, and kept his obligations.
