If you are talking about the area I think (recently mentioned on Dio's), it just isn't true.

There are two ways for a minotaur to get out of the area you spoke of (assuming it is that one), that I can think of. One is easier than the keyphrase. One is harder.

I also wouldn't describe it as an instant deathtrap if you were unable to use either of these ways, because death in that area is usually a slow and painful process.

Finally, I wouldn't say the people of the area are friendly either. Just some are not hostile.
