Hi, , unfortunately, Alzheimer's can affect the inhibition control center (pre-frontal cortex) in the brain. So while his intentions may be great to not offend you, he probably does not have the control over himself that he once had. It's not him, it's the disease.
If watching the news is what precipitates this, maybe try getting him interested in another program, that won't be presenting opposing views, but maybe is more entertainment-focused. - Warmly, Donna (team member)
