Neither American political party is interested in Saudi Arabia being on any kind of ban list for reasons of US geopolitics, and this has consistently been the case since before 9/11. Remember how difficult it was to get any kind of official confirmation Saudis were involved? Remember how they were one of the big donors to the Clinton Foundation? If not treating Saudi Arabia as a terrorist threat is proof of racism, then almost every US politician is racist (and probably most of the US press too).

It's not so much proof of racism as it is proof that this executive order isn't actually about keeping America safe.
