Tolik you are mixing two different aspects at being jewish religious and genetic.
Having German genetics is exactly that German blood in your family. You don’t stop being that through dilution of marriage.
Second religion yes it’s choice but have you see people give land and donate to projects they don’t identify with?
On both of those counts Trump has jewish blood period not an argument just statement he’s great grandma was jewish that makes him 1/8 jewish genetically.
As for acts well reconconizing Jerusalem as capital and thier ownership of sized territory of west bank as israel without consulting senate or house approval against international law is about the biggest gift anyone could give israel. Hell they named a place in west bank for him. Let alone wars fought without proper approval.
This started as a statement of why it was stupid to call Trump supporters white supremist. Being part jewish genetically is pretty much a no go for support from those people carring that mind set.
Do I care if he is jewish no it has no bearing on good or bad just how he runs the country.
Personally I think he will be reviled not from the democrat impeach bs but the fact he sold usa food secirity to forgeiners and helped accelerate the collapse of usd as world reserve status through mismanagent and over use of sanctions where not nessisary.
