Of course whenever you have taxpayers paying for something for individuals, those taxpayers may properly decide to exclude undeserving individuals from receiving benefits.
What would be controversial is classifying people as undeserving for past actions that
(1) were and are completely legal,
(2) are not even considered to be bad by a large fraction of the country, and
(3) have nothing whatsoever to do with what they are being excluded from.
For some context, Wikipedia says:
> In the United States, depending on the context, the term "welfare" ... can also include social insurance programs such as unemployment insurance, Social Security, and Medicare.
https://en.wikipedia.org/wiki/Welfare_spending#United_States
But in any case, Medicare is literally denied to prisoners, which is an example of ... denying welfare benefits for antisocial behavior?
Do you really believe that denial would not be controversial?
About 1/3 of Americans have a tattoo [1]. Of the people without tattoos 66% say seeing a tattoo on someone gives them neither a negative or positive opinion of the person.
A tattoo on the buttocks will not cause skin cancer on the face. (There is a small association between tattoos and skin cancer but that is skin cancers at the tattoo sight, and it is not so much that they cause the cancer but rather make it harder to notice the cancer so it tends to be farther along before detected).
So I don't see how it could not be controversial to cut of Medicare to someone over something that a solid majority don't care about and that almost certainly has nothing whatsoever to do with their skin cancer.
