Earlier quoted context omitted.
I'm not sure this is fair to all people over 65. It sounds like maybe your relatives are much like mine, and I agree, my relatives shouldn't be voting either. If we're going to put up a discriminatory barrier to voting, I think it'd be more effective if it was education-based. People with no education make poor voting choices, as we've seen in recent elections.
I know people with masters and doctorate level of education in medical and chemistry and other highly technical fields who believe in UFOs, creationism (the 10,000 year old Earth variety), among other things (I even once met a physicist who thought everything about quantum mechanics was bunk and classical mechanics could explain everything). And I'm by no means alone in that. So that may be anecdotal experience, but…
There should be a registry of doctors who are creationists or believe other nonsense (I'll give the UFOs a pass depending on just how fervent their belief in them is; I mean, can you prove we haven't been visited? The evidence isn't very good but you can't prove a negative. If they believe they've been abducted, however, that's a whole different level. Of course, I also can't disprove their claim but I'd rather err on the side of caution and assume they have mental problems and find another doctor.).
I don't want a doctor giving me medical advice when they don't even believe in basic science.
>It all comes down to that better decisions are the decision I agree with, whoever the I in any given instance is.
Perhaps, but I think it should be obvious by now that people who decided to vote for Trump have had an extremely detrimental effect on the nation's economy and well-being.
