Trump has helped usher back a return of the Dark Ages. It isn't that he and the growing cabal of like-minded fascists necessarily believe the backward ideologies they spawn, but the doubt and disarray they sow provides excellent cover for their kleptocratic conspiracies. 

'Old taxpayer' is probably just that - an old guy who resents paying taxes. These guys can't put their finger on the source of their frustration and anger. They can't quite grasp that the people egging them on - people like Trump - are the cause of their miseries. Their gullibility makes them easy targets. Rather than heed the warnings of impending doom brought on by unbridled greed and corruption, they'd rather shoot the messenger. 

Next they'll be burning books  - or computers - to foster contempt for scientists, intellectuals and advocates of rational thought.
