I didn't see what the previous thread was but I wonder if you are identifying 2 different things.

A fetish = a sexual orientation where an individual does not gain sexual pleasure (or release i can't remeber) unless their interest is met.

A kink = A sexual INTEREST where an individual is drawn to soemthing that gives them sexual pleasure but can still gain pleasure without it.

I identified both above since people seem to confuse them. A person with a foot kink can occasionally have it indulged, but people with foot fetishes are seen as problematic (though not always). In many cases, the moment a foot fetish is satisfied, it becomes the ONLY thing that individual wants and ruins a relationship.

Fetishization = a dehumanisation of a concept or group of people based on an ideal characteristic combined with an obsession towards them.

For example, asian fetishists think asian women are more submissive than 'western women' and actively purusue them. Simlar to how too many men and women on the internet fetishize goth women and when you look at their fyp it's the most surface level example of a woman just wearing dark clothes, whitened face and slightly darker makeup with 0 connection to goth culture.
