See, to me this is as dramatic as some of the people from the other side who get upset about decorative cotton plants in a Walmart or whatever that was.
Political Correctness is a term "used to describe language, policies, or measures that are intended to avoid offense or disadvantage to members of particular groups in society. Since the late 1980s, the term has come to refer to avoiding language or behavior that can be seen as excluding, marginalizing, or insulting groups of people considered disadvantaged or discriminated against, especially groups defined by sex or race."
Being aware of how our words and actions can be insulting to someone, even when we did not know it, and particularly in regards to groups that are marginalized or discriminated against, is not "the first phase of destroying the first amendment," which is about government not taking away our freedom of speech, not private business or individuals anyway.
I've never seen any white liberals say that other people cannot do things on their own. Not one. And I know a lot of white liberals.
The South is known for goofy quips and sayings? Lots of areas in the country have goofy quips and sayings. Country folks out in the mid-west, Cali people, people around the Great Lakes... I can hardly understand some folks from New England. One difference is that the South happens to have a bunch of sayings that have roots in race and how the races interact, because of the history of the area and the people in it, so more of those might get called out more than a New Englander talking about a "banging a uey" or a farmer in Indiana saying someone "has a holler tail" or a California person saying "Dude, that's 909 as hell."
That post was over-dramatic. Just as there are over dramatic people on the left, there are as least as many over dramatic people on the right.
