Right on Dagwood!
If you review the OP, it is clearly a poorly veiled attempt to characterize Trump supporters as being susceptible to cult like indoctrination because they missed an important juncture in developing maturity - the implied corollary being that Hillary supporters matured normally and are therefore immune to cultish influences.
Unable to support this assertion, thread originator reverts to deflective rhetoric.
Shall we take up the Democrat Party platform point by point to explain the irrationality behind their thinking?
Case in point: The NRA was founded by former Union officers who wanted to address the problem of so many casualties in the Civil War attributable to poor marksmanship. Even in the 1800s the large population centers held anti-gun sentiments which could be later found in idealistic movements such as Neville Chamberlain's "Peace in our time". When war breaks out, it is the Churchills and people teaching our men, and now women, how to shoot who become the saviors of civilization and the Chamberlains are remembered for facilitating the invasion of Poland. While the NRA was shipping guns and home loaded ammo to Britain, the peacenicks wanted to negotiate their way out of the war.
But somehow regardless of the reality of history, the Dems perceive the NRA as a cult and themselves as emotionally and intellectually superior. They would have their own sons and daughters go to war never having handled a gun and the Second Amendment would guarantee the right to own and bear cell phones. The same cultural conflicts that existed between people from cities and people from rural America in the 1800s is much more solidified today and this can be seen in the maps of counties that voted for Trump or Hillary. The thing that defines this difference the most is cities rely upon government services more than rural areas. They have a vested interest in government expansion whereas government expansion is viewed as oppressive in rural America. Therefore, cities are predominantly Democrat and opposed to value systems associated with rural America such as firearms ownership. Do Hillary supporters think all of this through or are they only reacting to what they are being told? Something most people think of as being immature and culty.
If you can't support your argument based on reality then you resort to minimizing the other side by characterizing them as a cult. Samantha Bee's NRA skit is clever, funny, effective and rightfully capitalizes on the Scientology cult meme but it isn't intellectually honest and neither is this thread's OP.
