Sorry, no. "I couldn't care less" literally means that it is impossible to care any less about something. Someone may indeed say such a thing sarcastically, but, irregardless, it's meaning is nonetheless absolute.
That's my point. When denigrating something, consigning it to the status of something to be lower than something to regard, it is correct to say, "I couldn't care less." To say the reverse says something
is worth one's regard, which isn't what one says when one is making the point he was trying to make.
I assure you that I know the difference between the two, and when I say either one, I am not saying it out of ignorance. I say one to be precise, and I say the other when I want to be more sardonically sarcastic, but it either case, they both mean that I don't care - in the extreme - about something.
Then you're the only one. You're being intentionally nonsensical, which is great when you're doing the Who's On First bit, but poor communication otherwise.
As for Kwanzaa, well, which it's it? Fictitious or fraudulent? And why does it bother you that people want to celebrate it as a holiday?
Well, I guess fraudulent would be more accurate, seeing as it
does exist. But to put it alongside Christmas is obscenely fraudulent, and putting it alongside Christmas, equating the two, is what bothers me about it. Had the inventor of it put it in, say, March or July, and not tried to say, "This is
our Christmas, I could just roll my eyes and chuckle at it. If you read the history of it, you can't help but be offended when its practitioners promote it as another Christmas, unless you're an iconoclast like Namaste.
Regarding this never-changing, set-in-stone Western Culture that you seem to think everyone should be required to participate in,
Never said that.
the culture of the west in general and of America in particular has been evolving since well before Columbus confused the Caribbean with a whole 'nother continent. The civil observance as you remember from your childhood is not likely to ever happen again. The cultural base simply isn't the same anymore. 50 years from now people will be complaining that things should be more like it was back in the 2010s, the good old days when things were simpler.
I wish you weren't right about that. That's a lot like the discussions I have with Doug over at that other expediter forum about queer marriage and such. He says, "All you moralists are dying off. Pretty soon there won't be any of you left." I warn him that he's not going to like the way society looks when that happens, because social decay won't be limited to just that.
Similarly, I don't think any of us are going to like what society looks like if cultural decay continues. The Romans saw it happening to them and did nothing to stop it.
