Not all Orange supporters are Xenophobic, but plenty are. Disagree that no one is. This is a solvable problem that Orange wants to campaign on.
Nationalism has become a destructive doctrine post WWI and WWII. The world is too interconnected. Nations need to pursue their interests and be proud of their heritage but chest beating nationalism is an evil not a good.
Interventionism is also an evil but isolating the nation such that it’s us against everyone else all the time is as bad if not worse. There is a happy medium that doesn’t involve either extreme. Coalitions that are in, and serve our interests are good. The Orange go it alone policy isn’t good.
Tariffs have always proved destructive in the long term. They are also outdated solutions to current problems. Let the market work and things go better than when the govt is interfering and setting artificial barriers.
