Many proposals on sending people to Mars seem to (deliberately?) sidestep the question of coming back. Often they quietly assume that they simply won't come back.

Sounds like a reasonable assumption given the length and danger of the trip. I’d assume the first colonists to sail across the Atlantic operated under a similar set of assumptions.
