Oh yes you do!
Whenever you hear this “pious” mantra, ask them this question: So you do not believe Christ can return at any-moment? Almost every time, they will respond, “Oh yes I do!” Then they do in fact have a rapture position, and they are also denying other rapture positions (prewrath and posttrib).
To be sure, pretribulationism is not the only camp that affirms an any-moment return of Christ, most historicists and preterists do as well.
On a related note, see my recent pamphlet, “I Am a Pan-Millennialist.”
