No, I was answering Augustin's question by mentioning some 
BAD arguments I've heard about forcing voters to express 
preferences they do not have.  

I believe it's best to allow voters to express any 
ordering, not necessarily strict, and to allow them to 
truncate their preferences if that can reduce the tedium of 
ranking a huge number of alternatives.  See the Feasibility 
criterion, the Minimal Defense criterion, and the 
Truncation Resistance criterion described in my website.
