I think these labels on peopple's viewpoints are not only inaccurate but unhelpful. Why is wanting adherence to immigration laws "extreme" anything? Why is wanting to become more insulated from events that occur a thousand or more miles away "extreme"?
The article notes France's unemployment woes . . do you think admitting more people into a countru helps the employment stats? I think it would worsen them. And, does it help or hurt a country to have sizable portions of the population to whom French culture and laguage means little? Again, I think it hurts that country's stability and solidarity.
World leaders have drug their populations into the illusion (now realized) of properity through globalism. What we have seen since the economic collapse of 2008-2009 has been that globalization can hurt as well as help a country's economy. I bet a lot of people in Western countries wish they were as insulated as Brazil is . . . Brazil hasn't gone through the crisis that so many other countries have becaquse they didn't buy into globalization. Is Brazilian leadership "extreme"? Is so, I think extremism can be very beneficial.
