Why would that stop anything? I spent half an hour over Christmas explaining to an aunt why the circle game [0] wasn't a white supremacist thing. All because the media chose to fall for the most inept trap ever planned: https://en.wikipedia.org/wiki/OK_gesture#White_power_symbol
This only gets better when people start to talk about specifics and be (to use your word) sensible about things. Drawing up battle lines trying to make the people you don't like take a stand with the SJWs is making things worse.
No, it wasn't. It was invented by the Left, unironically. They would call themselves Social Justice Warriors. Many leftists still proudly maintain that they "fight for social justice". Same energy. It was only later that the term was used derisively by the right, putting the term in ironic quotation marks.
It is exactly the same as "fake news"; originally used by someone in the lefty media (CNN?) to deride Fox News, but popularised by Trump against CNN. Or did you think Trump came up with that all by himself?
This is pure bullshit. "Fake news" was first used to describe completely fictional news outlets writing about fictional people and fictional events, mainly designed to go viral on facebook for ad revenue.
For example, Paul Horner[1]:
> His stories had an "enormous impact" on the 2016 U.S. presidential election according to CBS News;[17] they consistently appeared in Google's top news search results, were shared widely on Facebook and were taken seriously and shared by third parties such as Trump presidential campaign manager Corey Lewandowski, Eric Trump, ABC News and Fox News.[18] Horner later claimed that his work during this period was intended "to make Trump's supporters look like idiots for sharing my stories".[19]
> In December 2016, while speaking on Anderson Cooper 360°, Horner said that all news is fake news and called CNN "fake news", which was one month before Donald Trump leveled the same criticism at that network.[23]

This is not correct, and not what you are saying now.
