Which ones? The ones that allow raping of children by their leaders?

Or the ones that promote violence in their holy books, like killings and torturing to death? Oh, but the profanity! Not the profanity.

BS: Bologna Sandwich. "That's a load of bologna!"

What is the danger of explaining the word "bullshit" to children? Of course like many topics it should be explained carefully e.g. reading Frankfurt before discussing this specific paper.

And religion can politely go fuck itself when it comes to deciding what words professional academics use. They did that long enough already... But actually I know a few religious philosophers and they use the term without complaints.

Most children are eventually educated on these words. Usually by 1st grade, if I remember right.

What you're thinking of is what parents think they want reality to be, not reality.

If we're trending technical in our etymological taxonomies, then the X-words are all slurs because they insult people for belonging to specific groups. As you say, profanities and blasphemies need to address the sacred in some disrespectful way. I believe that leaves... curse words and expletives as the remaining categories of naughty words. Any others? I suppose vulgarity and obscenity, but those feel like subtypes of expletives to me.

I'm just an individual, so my opinion may be just that. My opinion.

To answer your question, families may ban the use of said words in the sanctity of their own homes, for example.

The only reason I may feel that curse words are inappropriate in any situation is because I'm already conditioned, from childhood, to think of them as "they may offend." But if no such conditioning existed, I'd say they would be okay in any instance, because the words per se are not offending. The intent is.

Take, for example, an eulogy. A person speaking of someone who recently passed away, may say "Excuse me everyone, but gosh darn, why did he have to leave so soon? I feel like a failure, because I could have done more. I'm a failure!" Why should it be different from "Excuse me everyone, but fuck, why did he have to leave so soon? I feel like I fucked up because I could have done more. I'm a fuckup!" Really, the only reason we may silently gasp at the second version is because we were conditioned to "gasp" at those words while growing up. Not because the words cause actual psychological, irreparable harm.

You touched the topic of religion in other comments. I guarantee you that when God, before killing everyone with a flood during Noah's ark times, I'm sure He at least, at the very least looked at the state of the "failed world" and said "well, shit!"
