A true believer is someone that blindly embraces a religious or secular ideology without questioning the underlying tenants of that ideology. We see this particularly on the left. For example the gay indoctrinated progressives are now supporting the Islamic group Hamas, totally unaware that most Muslim theocracies throw gays off of roofs to their deaths. We see it with progressive snowflakes that embrace the Green New Deal -- Electric Vehicles, ending the use of fossil fuels etc. -- not understanding that there is no Anthropogenic (man made) Climate Change and that such policies impoverish both individuals and our republic.
Is Trump an anti-globalist?
Well said. Deprogramming is no longer possible in our post modern consensus dialectic culture.
