Except that in the case of MI, the reasoning actually *is* because the 
author doesn't like it (translate, views as evil), and there is probably 
reasoning behind that (namely, experience with MI).  The view that MI is 
evil does not come from just some random political cause, trying to 
eliminate MI from all programming languages.

My whole beef with superdan's post is not with anything technical he said. 
I think what he says makes a lot of sense and was very interesting.  The 
problem is the way he bashes the answerer, who is stating what he believes 
is the reason.  In the interests of keeping this a civil forum with people 
not afraid to ask questions or not afraid to speak their mind without 
getting a barrage of mean-spirited obscenities, I think superdan needs to 
tone down his posts.  It's not a healthy environment for productive 
discussion.

FWIW, I have no problem with obscenities (not that I'm encouraging that, 
generally it doesn't get you as far in life to swear all the time), but I do 
have a problem with bullying.
