I appreciate you taking the time to respond thoughtfully, even though we probably aren't going to meet in the middle.
Regarding scare quotes: your usage is exactly what is meant by the term. See https://en.wikipedia.org/wiki/Scare_quotes.
Casual time is meant to be taken literally, it's not some special jargon, just two words put together. I also clarified the meaning in my previous response.
I don't think anyone but the NYT article author is conflating poor social graces with introversion. My response to that was to unapologetically insist that it is not a matter of rudeness to find socialization burdensome, nor to decline that burden when it is not necessary.
> More generally, there's a worrying trend these days to apply labels to yourself or others to justify being a jerk. "It's ok because I'm/they're/it's an X"
I cannot relate to this worry, it's not something I experience. But in case it's not clear, that is in no way what I was saying. In this context, I would say:
- I am an introvert. That's a fact about me, can't change it, don't even want to most of the time.
- I don't think declining social events is being a jerk. Regardless of whether one is an introvert or not, or whether one is motivated to decline by said introversion.
