Would it have helped to instead be told that you have poor comprehension skills and limited understanding of nuance?
Because that’s clearly the case if the above quote describes a conclusion that you reached.
People get the wrong idea because they want to. They're not turning into fascist racial and gender supremacists because someone was mean to them.
That's just who they were all along, and all it took was someone to come along and exploit that, and for others not to do enough about it.
We can argue til the cows come home how true it is or not, but it has played a role in what we're seeing unfold.
I don't know why the genuinely irrational, harmful things these people believe somehow means that I shouldn't be angry about immensely worthwhile and beneficial programs being shut down on the whim of an unelected billionaire.
Founded on stolen land is historically accurate AFAIK.
Slavery was practised in some regions but I don't remember being told that the US was founded on it.
I have been told that some sections are racist and sexist, especially in so-called "red" states. These beliefs seem to be whitewashed by right media using euphemisms like "all lives matter" or "pro-life".
But the nation itself was not painted as sexist or racist. Indeed, it was often described as mostly welcoming of all races and immigrants.
I don't think it's been called an illegitimate nation and don't see it as such. Rather manipulative and bullying. With bad healthcare and ruthless capitalism. But still a better values-based policeman than the USSR or Russia or China.
I see Trump admin as a higher level success of the racist sexist sections. It is destruction. But by the wrong section of society on the better sections. I see it not as restorative justice but as a path to worse future injustice.
Are those who talked about all this to blame for these consequences? Observing a phenomenon to analyze, criticize, and predict is something we all do. They were just the messengers of a phenomenon that was already in motion.
The phenomenon was irrational brainwashing using euphemisms and disinfo to whitewash unethical ideas, done by the US rightwing media and its corporate backers.
How exactly did a country that elected Obama twice fall to this brainwashing? How exactly did the liberal media fail to counterbalance the brainwashing? Perhaps you could excuse it for the first Trump presidency, but how exactly did all the smart, well-intentioned liberals fail to address the problem and stop it from happening again?
They failed to offer any hope to the people who were seduced by the dark side. Liberals failed. And to keep characterizing this failure as simply a "successful brainwashing by the other side" you completely remove any responsibility from the "good guys". And even worse, you completely remove any opportunity to learn from the situation so that the "good guys" can do something different next time. You've turned the entire left-wing political and media apparatus into hapless innocent victims of an evil empire, who were faultless in the face of an all-powerful right-wing brainwashing regime that had absolute power and was impossible to defeat. That's the most childish of assessments possible.
