Yup, there are three schools of thought.

Premillenialism, Amillennialism, and Postmillenialism.

Most Evangelicals believe in Premillenialism (thank you Left Behind Series) so the grandparent is correct they believe they won't be around for the acts of Revelation. But they are also super paranoid about this stuff and see things like this (and the adoption of stuff like this) as signs that the End Times are coming.

Plus, no one really know which will occur, and there's a field of thought that believe by taking the Mark of the Beast you won't be saved anymore (again, thank you Left Behind series) so they are SUPER paranoid.
