Of the choices offered here, I like "precarious", "unstable", or "fragile". I just thought of "risky" myself. Good, experienced mathematicians will know when it's okay to take "risks" (and will be aware of what the risks are). "Unstable" seems like a very sober choice, not too likely to ruffle feathers. I encourage anyone who cares about this issue to take a look at the current discussion at the nForum: http://www.math.ntnu.no/~stacey/Mathforge/nForum/comments.php?DiscussionID=1... You will see that opinions are divided even among workers in the nLab.

Let me start by proposing "equi-unstable" and "precarious" as possible replacements for "evil".
I agree that we should explore various options. Strickly speaking, there is no need for a new terminology since "non-invariant" has been used in the past and it is working pretty well. Let me draw a list of potential names. I have added a few: non-invariant equi-unstable precarious unstable fragile private I invite everyone to contribute to the list.
