Keep in mind that all voting systems have this flaw. It's just that
in Condorcet/CSSD, it is difficult to exploit. So sometimes I say
"this system allows strategic voting", when I mean "this system
makes strategic voting much more effective than Condorcet/CSSD". I
think this is still an important distinction.

Right, again what I really mean is, I oppose a system in which
insincere votes for the default are more effective than insincere
votes in Condorcet/CSSD. The proposals which include early
elimination of options beaten by the deafult (possibly with
a supermajority requirement taken into account) have this property.
