Interesting comment Bullwinkle. If you look at "far-right" and "far-left" regimes in history, you find that the worst of them are murdering dictators and will do anything to stay in control. North Korea's regime is called extreme right and left at the same time !! And is there a difference in outcomes between Hitler, Stalin, Pol Pot etc. Castro is viewed by many as a murdering dictator, but feted as a saint by others. Winners are grinners I guess.
You are correct in my view that right vs left is all about economics; and is more about a free market capitalist economy vs a progressive socialist economy. Both are usually in favor of open door immigration, but for very different reasons, one is about cheap labor to satisfy the return on investment and shareholder profit and the other is about fairness and equity for all.
The danger of Ms Le Pen is that she like Pauline Hansen tries to win support through division and hate. Her vilification of Muslims in France does not create harmony or build communities. If France goes with her as their Leader, what happens next? Are all the Muslims banished ? Or do they make war ?
The world is in for some very turbulent times.
