I know you didn't say they are (can be) racist, I am. I'm disagreeing that they are uninformed; a lot of Asians actively side with Trump and Musk. I know this because I am Asian myself and hear it from my parents and their friends who are Pro-Trump, anti-immigration, and racist against Black people, Hispanic people, Brown people, Muslims, LGBT people...
My dad defends every accusation against Trump. He thinks every bad thing said about him is a lie made up by his enemies. My mom's best friend loves him and says he's so smart, and everyone who disagrees with him is too stupid to understand.
These people would be surprised how many people have preserved multiple portraits of Hitler and hidden away in their homes and shops. I'm talking about stamp collectors. There were very many stamps issued with Hitler's gave on them, and very many casual to dedicated collectors own at least one.
Having a shrine to Hitler is not fine. Owning historical items in context is totally fine. Authentication and appraisal is a normal part of insuring any kind of collection.
The real issue is not that a politician has one Hitler-related item amidst a wider collection of rare, historical items, but that someone who is independently wealthy and can spend millions of disposable dollars on a hobby is representing "the people" in a time of rising unemployment, affordability crisis, housing crisis, cuts to essential services, etc.
