Imagine if someone asked a candidate what they would do about terrorism, and they said "I have one bit of advice: avoid major cities, and don't fly on airplanes unless you absolutely have to."
Now do you understand what's wrong with this?
(As an aside, I just noticed that Kasich used the word "coeds" to refer to female college students. I didn't know anyone still used that word in that sense.)
What if a major candidate said, "If you don't want to get your head cut off, don't travel to countries where ISIS is in control."?
This bastardized travel analogy is cute, but utterly disanalogous to what is being discussed. If Kasich said: "don't go to the frat house full of known rapists that rape everyone who come through the door but hasn't been shut down by the cops for some reason", it might be valid.
