I would need to see an example of the term being used to identify what you believe is phony and substantial positioning on an issue. I've only ever seen it used when social issues are brought up that have offended a group of people and is used to describe that group of people.
For instance -
Amazon Warns About 'Racial Prejudices' In 'Tom And Jerry'
Amazon recently added tom and jerry with it's originally aired episodes. This means that it includes the representations of attitudes that existed 70 years ago. As a result they added a disclaimer identifying that Tom and Jerry have ethically dubious episodes that deal with racial perception.
People, as you can see in the comments, are calling this pc. Which i find ridiculous. The imagery of black face and other stereotypical punch lines that are made at the expense of a people in the show can be a bit a jarring to those that it hits closest to home to.
That why I pointed out that it's usually the privileged class that cries PC. Notice the racial make up of group who is crying pc and the group who is seeing it for what it is.
This is something I've noticed for many discussions in which the phrase PC is thrown around. Typically those who endorse or are otherwise unaffected by the issue take the stance of indifference, while those who are effected take it seriously.
