A parallel to anti-vax slur is isolationist. If you are opposed to the war state you are an isolationist. Even if you favor free trade with all nations and people. People that use these slurs expose their ignorance of thoughts outside of the narrow band of acceptable opinions. I'm always underwhelmed by people like this. People like Ben Shapiro. What's even more underwhelming is people that act like Shapiro is some extremist when he's really a rather boring Republican talking head that owns inexperienced college progressives in their twenties.
