i don't get it.

of course, if there are only two candidates, there is no problem with 
Plurality (because it's also a Majority).

so how is Plurality so flawed if we accept that a two-party system is 
fine and dandy?  if not Third parties, for Independents?

what is the scenario with two parties where FPTP is so flawed?

just curious.

(i still reading what you guys have written.)
