Or, to rephrase that slightly: why is it so hard for other people not to agree with my view of the world? That's the essence of being PC. Recognise that I know best.
That's particularly important in a thread that's likely to flare up at any moment. Flames have a lot of energy but intellectually interesting they are not.
> Treat others with respect.
I guess you're implying that you disagree and that you should be a dick to everyone else?
>> Treat others with respect.
No, the OP's comment was much longer than four words, and part of it implied that if you're not PC then you're a jerk.
It's a lot easier to see the problem with the OPs comment if you think about what it means to be good, and how the definition of "being good" can vary so much between people.
If you want to talk with people about what being PC really is, you have to use fewer vague, high-level abstractions like "jerk" and "respect" and more concrete examples.
And that's what PC is: we're the nice guys; anyone who disagrees with us is engaging in hate speech; so let's just gag them and send them to Antarctica.
PC is essentially totalitarian. One point of view, no arguments.
