Blocking citizens from venting their concerns, because of political correctness, is as dangerous as can be.

I just came back from a week in Sweden

If political correctness blocks the discussion of citizen’s ordinary and very human concerns, whether these are right or wrong, like those many have on what they feel is an excessive immigration, and the risk of diluting the meaning of being a Swede... that is a great growth-hormone for extremism.

In other words, if you use a “That’s like Hitler” in response to all of their concerns, then too many might end up thinking “That Hitler guy sounds having been quite right to me”.

Never forget that the emotions involved in the not liking something for the wrong reason, can be just as strong as that of the not liking something for "the right reasons".

Political correctness could, in the best of cases, be a type of Neo-Victorianism... but, unfortunately, it seems more to have become the Neo-Inquisition of our days.
