If you think that communist/socialist language has taken over culture I think you are not really paying attention. First of all, you might want to read Shaw Communications, authoritarian personalities are far more likely to be right-wing (which means against gun control) in the states.
You want to talk about ‘gun nuts’ being a common term, what about “taxpayer” which is basically the universal way that citizens are now described - a term that essentially accepts that our worth as people is equivalent to the money we possess. Language has been infiltrated by a lot of loaded terms. Frankly, a lot of gun nuts are called gun nuts because they are pretty nutty. Then the term is generalized to apply to everyone who owns guns, but that’s an example of seeing the world in black-and-white, us-vs-them terms, which, again, is more of a right-wing mindset. Besides this, gun control has nothing to do with the economic system of the country - communists could have lots of guns in their society and capitalists could have virtually none allowed. America is the country where ‘guns’ is right wing and ‘not-guns’ is left wing, and even then that’s probably too simple.
The soviets may have defined disagreeing with their philosophy as a mental illness, but americans defined not wanting to be a housewife as a mental illness that needed a lobotomy and recently defines mental illness as whatever the big pharma companies have made a pill to cure. The definition of mental illness serves people in power, whether those people are communists are crony capitalists. Who is subverting this notion by presenting mental illness as a thing we want to understand and people with mental illnesses as people we should care about and respect? Why, it’s the left-wing pinko commies (who don’t want you to have guns, except the ones that do).
Recently international forum research showed that many Americans think that the gap between the rich and the poor is one of the biggest problems in America, and 60% think that raising taxes is the best way to address that. Where are all the politicians rushing to raise taxes? While I don’t doubt that progressives will once again have their day, right now the idea that some kind of communist idea is winning against capitalism (which in America might as well be the equivalent of “racism” in that it is merely a prejudice based on how much capital a person has) is fantastical. A more collective, interdependent view of society is eroding this notion slowly, but that’s because the current system of doing whatever the rich people say is a toxic, nearly totalitarian system.
I don’t want to be communist or capitalist, I’m just saying that the idea that the idea that communism-for-all is winning right now is disconnect from reality.
