Omicron is much less likely to hospitalize people, it never reached a concerning level in South Africa and cases are falling fast. I could see wanting covid patients to pay for it themselves, but denying them entry is ridiculously cruel.
Extrapolating SA findings to other countries may be premature, though the actual severity of the Omicron variant remains an area of intense interest and investigation.
Mild or otherwise, the US will all but certainly know within a month. Wishing for the more convenient answer may prove harmful or deadly to many.
To clarify, rather than denial of entry, I am suggesting deprioritization in the ER.
If someone got into a car crash tomorrow and the ER is full, given a similar expected mortality between the crash victim and antivaxxer, the antivaxxer should be ejected to make room.
Today we are already seeing that antivaxxers are saturating ERs and people have to wait hours for serious issues. I do not think it is particularly controversial to say that the antivaxxer is less deserving of care.

Many people do not even do the "bare minimum" as a member of society, and they should be treated, to the greatest degree possible, like the people who do the maximum, or even just the usual. High-tax paying people, beloved teachers, famous artists, despised criminals - they should all be treated as humans, with the appropriate medical treatment according to their human needs, not their moral failures or victories.
People are the product of society, and a component in it, and they should not be judged by stereotypes, or even judged at all, when it comes to responding to their medical needs. Ideally, we'd take this approach in every area of life, but this is especially justified when applied to injured and sick people. "Misguided" is a more useful frame for many people than "evil".
Triage by prior behaviour is a poor basis for healthcare. Everyone has their own group of people they like less or more, according to their prior experiences. More importantly, the time to judge someone's moral behaviour is not at the point of healthcare delivery. Even if mistakes never happened, and your moral views are correct and correctly applied, it wouldn't be right to apply this rule because it would be the first step away from neutrality.
The status quo of neutrality is a good rule, even if on rare occasions it results in seriously injured violent criminals receiving medical treatment ahead of sick nuns. Because almost all of the time it's the rule that is the most human, on our best behaviour. And especially so when we consider that many of our own views are not solely attributable to our individual choice but are in fact strongly influenced by our place in society. Once immoral individual behaviour is the yardstick for medical behaviour, perhaps based on views about groups, it's difficult to know when you've strayed off the moral path.
Not to mention the associated dangers to staff that come along with the non-vaccinated population. My sister is an ICU nurse in a C19 ward, and has been threatened many times, screamed at countless times, by families of people with C19. They are all, as near as she can tell, of a certain tribe.
But if you talk to nurses, visit r/nursing, etc - the sentiment is clear. Front line workers are sick of having to prioritize antivax bed-wasters over people with real issues.
