golf: a willful misuse of a perfectly good rifle range.
I've been saying this for years! I had to take a golf class in college (it was a required course, amazingly enough) and took perverse pleasure that all the supposed benefits from golf could also be found fishing (if you fish from a muscle-powered boat). In my very, very (very) late 30s and I've still never played a round of golf in my life.

Whatever passes for Top 40 music these days. I'm not sure if Dua Lipa is a person or a band or something that requires surgery - I think maybe a person? - but it sounds unpleasant.
Most 'reality' television. Especially shows about a topic I'm interested in, like gunsmithing or barbecue, that don't teach me anything about the topic at hand because they're rambling on about what JimBob said to MaryBeth's cousin's girlfriend's baby-daddy. Worst Cooks in America would be a much better show if Alton Brown ran it and made it as educational as Good Eats.
Celebrities. Like, caring about what a famous person does in their private life so much that there are multiple magazines and television channels devoted to the topic.
Following, and emotionally investing in, the drama in the Royal Family. Fine, Canucks, that's your head of state, but Americans? Have some self-respect.
Televised trophy hunting is something I actively dislike because it rewards and legitimates horrible sportsmanship. Taking a 90-yard archery shot at a buck or a 200-yard offhand muzzleloader shot at a moving antelope because you have to kill something before the production deadline is reprehensible, and Outdoor Channel shouldn't reward such conduct with air time.
In a moment of self-awareness, hobbies I enjoy which I'm sure others would rather I don't talk about:
Saddle hunting
History podcasts
Minor league baseball (especially St. Paul Saints, Fond Du Lac Dock Spiders, and Los Tecolotes de Los Dos Laredos)
Motorcycles
Politics
Guns
