Oh come on. You deal with customers and you choose to use swear words, and you’ll probably find yourself out of a job. You and every other human being already deals with language policing. PC is simply a change of acceptable words to widen unacceptable language to include those that are unacceptable or are seen as harming various minority communities.
Perhaps what you are complaining about is that we were raised in the dominant culture, so we grew up policing socially unacceptable language automatically. How dare we be put into the position of everyone else of having to learn new speech patterns in order to continue to be socially acceptable! That’s everyone else’s job!
More seriously, it’s time for us to grow up, accept that we live in a multi-cultural society, and make some effort to deal with that reality. It’s what everyone else us around us is capable of.
Society in general. Any language policing needs acceptance from a significant segment of the population in order for there to be impetus sufficient for actual enforcement. Most attempts to change fail - we only hear about the ones that have gained a wide spread of usage and support.
Of course, it’s always your right to ignore the general consensus and pay the consequences.
