Most voters have ten second attention spans as well as understanding PR is more complicated than what we are used to.  A lot of those at fairvote.ca seem to live in a bubble and don't look at how things are and instead look at things from a theoretical rather than practical point of view.  Most industrialized countries may have PR, but it's been there for many years and has not been without its issues.  Never mind Canada with its large land mass, low population density, and diverse population is quite distinct from pretty much every other country thus our system will likely be different.
