No. It adequately serves as a descriptive reference to the social dynamics involved in determining what is Right, moral, acceptable enlightened or otherwise good. If you can suggest a substitute phrase then I would happily adopt it. Arguments along the lines of 'something to do with political correct therefore something bad about the other side' are common. It is to be expected that some will assume a similar error of reasoning is being applied whenever the phrase is being used no matter the actual content and I would prefer to have a phrase that avoided this hassle.

The phrase you're looking for is probably "socially acceptable" or "social norm". The phrase "politically correct" is primarily used as a connotationally-loaded derogatory for social norms the speaker disagrees with, and to signal, in a beliefs-as-attire manner, group membership with certain political positions. If you want to criticize social norms, which I agree is a rewarding and enjoyable hobby, you would do better to name the specific norms you take issue with, rather than using a catch-all term for norms you dislike.

For instance: Which claims of exclusion are not acceptable to raise that you think ought to be? Why? What norms would you prefer?

I reject posts and certain of the normative demands contained therein on their own merit as I see it.

Okay. Which specific normative demands are you rejecting?

It is reasonable to desire an inclusive environment independently of the influence this improved environment may have on the spread of rationality. I for one accept inclusiveness a terminal value while 'spreading rationality' is not a goal of mine at all.

So you accept inclusiveness as valuable, but disagree with explanations given by individuals who felt excluded for why they felt that way, and feel that others are neglecting the spirit of mutual understanding across a cultural barrier? I'm not sure I follow.
