Without evidence, I reject your first point that it is posturing.
What evidence would you accept?
Your second point is nonsensical. Self-censoring is entirely different from suppressing dissenting view points. We've been through the college thing and there are other factors at play there.
The "self" is in parentheses. It's censoring and it's forcing people to self-censor in fear of social ostracizing.
Your third position has the same flaw at your second.
As in, it's nonsensical? This objection is nonsensical
And none of that explains why political correctness is a deserved or earned pejorative.
Yes it does, unless you think the three points are positive or morally desirable.
Text-book special pleading.
What made you think I was talking about human interactions in 1000 BC as opposed to how things are today?
I'll remind you that the last 100 years includes the Holocaust, two atomic bomb strikes, multiple genocides, lynchings, assassinations, segregation, terrorist attacks, torture, gay beatings, and anti-gay laws, which is not an exhaustive list.
You talked about special pleading, this is it. A type of cherry picking fallacy.
You're implicitly claiming here that the majority of human interaction has been through hate, aggression, destruction. I'd wager constructive interactions, social bonds building (trading for example) has been far more prevalent human interaction.
But again, the above is talking about what has expired, not what individual people in general aspire to be, which was my original claim.
I don't claim to know what the exact population break down is. I doubt the data is available. I do know that the idea that majority of people want to be polite flies in the face of evidence.
I does not. For example, the fact that I tend to get into fights does not contradict the claim that I
want to be polite. The whole point was that politeness is a morally desirable trait.
