The left have been using language to support their causes for ever so long, not just language but specially designed language to make the message more subtle and acceptable and positive to their cause. They are experts at this game. When things don’t work out with the words they use they change the words. Instead of liberal Democrats they now ant to be known as Progressives. I recall a few years back they used the words scheme and plan to describe the difference between them and the republicans. They had a “plan” the Republicans had a “scheme” They have used the language this way as long as I can remember. If the message doesn’t resonate one way, change the language but the message doesn’t change.
There are many examples of language use and one that I overlooked was and is their reference to Mexican illegals, they always referred to them as immigrants even when the topic was illegal aliens. Who could be against immigration,
so you hide the illegal aspect under the heading immigrant and you have won half of the argument. That’s the liberal way.
