I agree with the sentiment but not the idea that proportional representation is the answer. With PR we are more likely to get a larger number of small parties. Many will have non-mainstream views such as the ultra orthodox parties in Israel that push for Zionist policy such as building settlements. In the case of Israel they have undo influence on the Prime Minister as he needs their support to stay in power..

We have many checks and balances with the Parliamentary system that will ensure that no party in power is too extreme. FPTP has served us well for 150 years. I would be happy to consider something better - when I see it.
