Well, RSA is the asymmetrical cipher that PGP2 uses, IDEA is the
symmetrical one. Doing a "normal" encryption, both are used: RSA for
encrypting the symmetrical IDEA-key (which is used to encrypt the
actual message).
So you can't encrypt a message using RSA only. (Theoretically it's
possible of course, but PGP won't do that - IIRC).

They are right, as long as they are not using a (earlier by others
mentioned) modified Version of PGP.
