How to install democracy (in a country)?

Any ideas how to kill off the winner takes all thing?
It is really bad when someone gets 35 or 40 percent of the vote and beats
off the 3 others who got the other 60 to 65%. Ideal way  for little hitlers
to become big strong hitlers.
I come from the republic of Ireland. There, we have a thing called the
single transferrable vote which basically means that if the 35% guy is
nasty to minoritys or too bad a crook, they can gang up on him (in voting
terms) and prevent him from gaining power. The divide and conquer politics
of straight vote countrys is not so easy because if you try it, you create
2 enemys instead of 2 victims. It means that politicians in the south of
ireland have to use more temperate language than those in the straight vote
north. Rabble risers find it difficult to gain power in the south. Here in
BC canada, the provincial government has decided not to bring in a law
which would have allowed landlords to raise rents (and backdate the rent
increase for 3 years). (We have the straight vote in canada) The BC
liberals got 77 of 79 seats on just over 50% of the vote last time.
They have absolute power without check and it has gone to their heads.
In Ireland by contrast, a party cannot get such power because there are
generally one or 2 alternative governments possible. Not just the tired old
right wing, left wing thing that we have here (with the moderate centre
vacant). Anyway, just wondering if there is a practical grass roots way of
dilivering change to a stupid old system that brings crazy swings from left
to right every 8 or 10 years? 
By the way, I come from a minority in Ireland, I felt protected by the
electoral system and I met a lady from here and that is why I left.
(Fending off the "if it was so good why did you leave?" stuff before it
starts!
