Who ever said fetishes were bad or abnormal? Is this your opinion?
No, this is the definition of a fetish:
1 a : an object (as a small stone carving of an animal) believed to have magical power to protect or aid its owner; broadly : a material object regarded with superstitious or extravagant trust or reverence
b : an object of irrational reverence or obsessive devotion : prepossession
c : an object or bodily part whose real or fantasied presence is psychologically necessary for sexual gratification and that is an object of fixation to the extent that it may interfere with complete sexual expression
In the end it doesn't really matter. The person is still gay. They should be allowed to pursue whatever activity makes them happy. You know, "Life, liberty, and the pursuit of happiness" that's a notion that will always serve as a great model. No matter what, some intolerant members of society will still hate others because of their behavior. The label you place on it won't change this fact.
Labels make all the psychological difference in the world to those they label.
