Hi Eduardo, You asked, in full: "Seriously, do you really think so ?" Earlier you asked, in part, "What happens with readers which see "x" and do not belong to our group ?" You pointed specifically to the the word "evil", which seems to be driving this conversation. I answered that the reader could go to the nLab. At the nLab the reader can either read about the term or take part in a discussion concerning the term. Even better, the group of people who most often use this term might be hanging around to discuss the term with the reader! Other than pointing out that the confused/interested reader could read about and discuss the term, I don't think I made any other claim regarding use or introduction of terminology. So, I guess the answer is yes, of course, I am serious. Did you have some reason to doubt my sincerity? Best, Alex [For admin and other information see: http://www.mta.ca/~cat-dist/ ]
