I guess it depends on what we mean by standing against the mainstream.
He speaks against the fraud that system is, but like most in their American mainstream he still supports their political system as fundamentally legitimate, because it allowed him to become so wealthy.
He is not willing to oppose their system in a meaningful way that his father did - by trying to damage its main source of funding and control, which is the #IRS and its unconstitutional functions even under their phoney, bogus #constitution.
He isn't willing to martyr himself the way his brave and principled father did!
