That being the case, can I just keep folding back a 120 foot insulated wire
dipole until it is say 5 or 6 foot long and it will still be resonant on
the original frequency?

if it is insulated wire it must be cut, if its not then it doesn't.

you will see some effect of folding it back even with insulated wire it
won't be the same as cutting the wire shorter.

No one said it would be resonant on the SAME frequency, just that
there will be some effect. I have heard about an antenna design for a
shortened dipole using 3-conductor home electrical wire. At one end,
the green is connected to the cobra-head and the black and white wires
are soldered together. At the other end, the black is soldered to the
green. Viola -- a linear loaded dipole!

I haven't tried it, but if it works, you may very well get your
desired frequency with folded wire. I would strongly suspect it will
be a compromise antenna as opposed to one with a gain, though.
