Did they claim that the American west had no atmosphere, water, food, topsoil, or life of any kind, and only 38% normal gravity?
If you want to see extra planetary colonization, the moon is the most obvious first step by a HUGE margin, and even if it was made of gold or some other precious material, it wouldn't be financially sane, but the advantages mars offers pale in comparison to the EXTREME disadvantages its immense distance offers.
IF we can get something going on the moon, it makes literally everything else magnitudes easier. Doing anything else is, at best, a pointless exploration mission, and at worst, suicide by government spending. None of the mars plans are remotely realistic or grounded in reality, and all have so many points of failure it's going to be more worrying if we actually think we can get someone there.
It does not have to be an either/or mutually exclusive thing.
Do not ignore the importance of psychology and symbolism in long-term, cooperative human effort. A moon base that people can visit and inhabit will make concrete what would otherwise be an abstract concept. It will be much easier to get funding, buy-in and cooperation from an Earthling who has been to the Moon than from someone who at best sees anything happening in space through screens.
