This edit (Revision 4, to be clear) removed the phrase " Welcome to the reality." from this answer. If I am not mistaken, I had previously rejected this or a very similar edit to that answer. In my view that phrase indicates that the assumptions behind the question are, in the opinion of the user posting the answer, naive. As such i think it is a significant part o the author's intent, and should remain. I almost rolled back that edit, but did not want to edit-war.
Should this edit be undone? Should similar edits be acceptable in the future?
