fet·ish noun

1. a form of sexual desire in which gratification is strongly linked to a particular object or activity or a part of the body other than the sexual organs.

2. an inanimate object worshiped for its supposed magical powers or because it is considered to be inhabited by a spirit.

cult noun

1. a system of religious veneration and devotion directed toward a particular figure or object.

2. a relatively small group of people having religious beliefs or practices regarded by others as strange or sinister.

3. a misplaced or excessive admiration for a particular person or thing.

So, it’s either sexual or directed at an inanimate object. Trump is not inanimate.

Trumpism is a dangerous cult.

No, cult is the correct word. Fetish suggests that it’s sexual.
